Tested some loads from a ladder test on Thursday in my 260 with R16 and ELD-m’s.

Shot 20 at 1125 yards and chrony’d 15 in groups of 5.

All three had a SD less than 5!

Same accuracy, better speed, Better SD, better vertical spread at distance.

43.1 grains got me to 2800 in Winchester cases with #200 primers loaded to 2.94

Impressive powder!

We need more people in the 260 master race! I'm developing loads for my AI/AX with a 24" Proof CF barrel in .260. I did ladder tests today out at Quantico with H4350, H4831SC and RL16 using Lapua 136 and 139s, the 142 SMK and the Hornady 130 and 140 ELDMs.

Here are the results. I certainly think I could squeeze out some higher velocities in some of these combinations. Your mileage may vary. Next step is to take the nodes and work jump to a final load and BTO.

That is some solid data!

Question: why didn't you go any higher in charge weights? Is your chamber super short or you can't load past typical mag length?

I've shot Nosler 140 RDF and started testing with Berger 140 Hybrid, and I'm finding loads at 44.0 gr H4350. I'm loaded a touch longer at 2.880" to 2.950", but I'm not seeing pressure signs until 44.7 and 45.0. By the way, this is Lapua brass and CCI BR-2's.

I didn't find any good data for a 24" Proof CF barrel in 260, so I worked off Quickload and to velocities I thought the barrel would like, e.g., 2750 - 2850. I know there's more out there, but for now I'll load to nodes and tweak jump. I shoot square range to 1,000 (at Quantico) so I don't need to be throat burning fast, just vertically consistent.

I had BTO measurements for all the rounds (except the 140) so I loaded 0.020 off the lands, and to 2.800 for the 140s (virgin Lapua brass with F210Ms).

When I run your 44gr load in QL, it's telling me it's at 66,599psi (over max pressure) in a 24" barrel at 2.880 while delivering 2843fps. I'm not sure I need to run a 140 that fast, but that's why I'm here, to learn even more.

Out of curiosity, what does Quickload say a 44.1 grain dose of H4350 behind a Berger 140 Hybrid at 2.950” In a 26” barrel is? That’s in Lapua brass, CCI BR2, and 0.030” off lands.

I had a MagnetoSpeed V3 strapped onto the end of a TBAC 30P-1 (9”) suppressor on the end of a Bartlein 26” chambered in .260 Rem with a 0.145” freebore. In 92* F and 2750’ DA, it measured the following:
Berger 140 Hybrid, Lapua brass, CCI BR2, 2.960” and
43.5 gr H4350 2886 fps
44.0 gr H4350 2940 fps
44.5 gr H4350 2949 fps
45.0 gr H4350 2998 fps

Hodgon Reloading lists a 142 SMK and 44.5 gr H4350 at 2.780” OAL as max just under 60K psi.

You broke Quickload bro...no, not really.

A berger 140gr hybrid, seated to 2.950 in brass with 53.5grs of capacity (my estimate), 44.1grs of H4350, in a 26" barrel at 92 degrees ambient says 2893fps at 66,417psi (6,417psi over max) and a 3.6% compressed charge. If your case capacity is a bit less, the velocity goes over 2900, but pressure goes up. Add 25fps for the suppressor and you may be close to your results???

I'll have to look that Hodgon SMK load up and QL is saying a 260R, 142 SMK and 44.5grs of H4350 in a 24" barrel at 70 degrees is 2931fps at 72,738 psi, that doesn't seem right....

I know I’m close on pressure limits, but it’s not a compressed load. 44.7 and 45.0 had some room to shake and no crunch on seating. I’m creeping into 6.5x284 velocities which worries me I’m into 6.5x284 barrel life.

Thanks for running the numbers!

@Defender3

I did some chrono work today. 82*, 2500’DA, 140 Berger Hybrid, 44.1 H4350, Lapua, CCI BR2, 2.950” averaged 2912 fps, 25 ES, and 8.1 SD. That was 15 shots.

 

[Defender3]

Here's a follow-up to the velocity nodes post. I took the 142gr SMK and loaded with H4350, RL16 and H4831SC, and at three differing jumps off the lands to test vertical dispersion.

As a reminder, here are the velocity nodes for the differing powders with the 142 SMK.

I took each powder and loaded 3rds at each jump for a total of 9rds per powder.

I shot them today at the 100y range as Quantico was closed. The weather was perfect starting at 64 degrees and no winds and ending at about 78 degrees and with a 5mph tailwind.

Here are the targets. I started with a 5-shot group of Prime factory to foul the CCB (top left, and shot the Bergers and H130s as the last groups of the day). I then shot 3-shot strings of the H4350 loads at the bottom set of dots (and used the riflekuhl between each string to cool the barrel). You can see the barrel liked the 2.2705 BTO so the H4350 load will be Lapua brass, F210Ms, 42.1grs and 142 SMK loaded to a BTO of 2.2705.

I did the same for the RL16 and you can see there is less vertical dispersion with the 2.2690 BTO, so I'll play with that a bit to verify it will be a good load. Last were the H4831SCs and you can see the barrel preferred the 2.2665 BTO. Given the 2.2695 results, where I may have pulled a shot, I may also load those up again just to give them one more try.

Having burned through two .260 barrels, but with over 8,000 rounds between the two, I can honestly say that I’m sold on the 2,750-2,800 FPS range for barrel life. I know, for certain that you can get great results at the higher nodes, but you will definitely trade off for barrel life while doing so.

It’s not a bad thing, it’s just a choice.

I did some chrono work today. 82*, 2500’DA, 140 Berger Hybrid, 44.1 H4350, Lapua, CCI BR2, 2.950” averaged 2912 fps, 25 ES, and 8.1 SD. That was 15 shots.

That’s getting right with it.
I can run that load in Winchester brass at that length which is at least 1 1/2 grains roomier which gets me 2820 in the last two barrels I’ve run.


I’m happy to be pushing 147’s at 2800 but I guarantee it over SAMMI pressure to do it.

Once I get my magnum barrel I’m going back to the range lash mentioned with 140’s

Brass and barrel life at that range is excellent and hot conditions/ammo is a non issue.

 

[Brandon05_88]

@lash
Is that 4,000 rounds in each barrel? What bullet and load combo? I shoot roughly 800 rounds a year. I’m fine with 3 years ~ 2500 rounds for a barrel.

@Steel head
What load to get the 147s up to that speed? I tested them with H4350 and H4831. 4350 hit pressure before that speed. 4831 seemed to have a mode at 2733 fps.

4400 in the first barrel, though admittedly the last 100 or so were mostly toast on the second day of a match. 3600+ in the current barrel. It’s still in there and shooting under 1 Moa, but time for a new one.

136 Scenar L over 41.8 H4350 in Norma brass with Fed 210M, going between 2750-2810 depending on barrel. Consistent as anything and easy on the brass. I can easily get 2900 with these, but like the combo I have that works.

R16 is the answer.
The data is above in a previous post.

 

[Defender3]

I know this isn't exactly germane, but I have 4,500rds through my 260 gasser and it's still going strong. I primarily shoot factory H130s as it luvs them and they clock out at about 2775fps.

 

[lash]

R16 is the answer.

I know that this has been asked and answered before, but how temp stable are you finding the RL16?

 

[Steel head]

So far It seems at least as good as H4350.
I’ve only run it at about a 40 degree spread so far and haven’t seen any appreciable speed difference in that range.

 

[Defender3]

In case anyone wants some factory data as follows. I'll post up some 260 reloading neck tension data later today once I can pull out the labradar velocities.

I shot some current production Berger/Lapus 140s and 136s yesterday at Quantico, and the original Norma/Prime 130s. AI/AX with a 24" Proof carbon fiber barrel in 260R. 2/3rds IPSC steel at 1,000. Exceptionally calm day to start, then winds were at 8-12mph and swirling.

This is when it was exceptionally calm and no mirage. Both with center holds, Berger 140s in the shoulder/neck and the Prime across the belly. The Bergers were averaging 2754fps with a spread of 35fps and a SD of 11fps. The Prime averaged 2865fps with a spread of 48fps and a SD of 17fps.

This is the Berger 136gr Lapua Scenar-L. I had a good group for the first six shots and then the wind started swirling leading to two shoulder hits (left and a nick on the right) and two misses. The 136s were moving at 2833fps with a spread of 30fps and a SD of 7fps.

While I'm now going to reload for this barrel, these Bergers (and the FGMM 142 SMK) just shoot well for factory. Provided FWIW.

 

[Defender3]

Long post alert. Guys, if this is too much for the thread, let me know and I'll stick to the facts.

I was thinking about the whole virgin brass versus 1x fired brass for neck tension consistency and volume, which is a brain worm a guy from another thread implanted. My original thought was case volume would only change slightly from virgin to 1x. But I didn't consider neck tension. I'm using Lapua brass which is prone to tight necks and dings in the necks (the last batch of 100 had 9 cases that had flat spots on the case mouth; they were recycled to sample cases for seating depth testing). Once you fire the virgin Lapua, you've opened up the neck a bit which could affect velocity and the consistency of bullet release. So, I preped and loaded some rounds...

Decapping 150 1x Lapua .260R cases:

Done:

Break out the F.A.R.T:

Load up the tumbler with the stainless pins ensuring they get inside and not on the floor; have you ever tried picking these things up?

Dump in the brass:

Add a touch of LemiShine and some Dawn Blue, which I can't find, which means the wife probably used it, which means I'm stuck with whatever this pink stuff is:

Fill it with hot water and I'm GTG:

Button her up and turn her on for two hours to clean up the brass. To be continued...

 

[Defender3]

The wet tumbling is done so it was time to clean the cases of the solution and get them dried. BTW - ALL steps were performed while the spousal unit was out of the house!

This is the color of the water after the carbon removal:

Dump the water and rinse a couple of times:

Watch those pins as they get everywhere and are a dead giveaway to the wife you were up to something:

Next step is into the wet/dry tumbler to separate the pins from the cases:

After a quick tumble, the cases are ready for drying in the $20 Walmart dehydrator, stacked three levels high:

After 15 minutes of heated forced air the cases are dry and ready for the next step. So, I now have 150 fire formed 1x Lapua cases ready for priming:

 

[Defender3]

Time for the next phase. I dragged out the Gempro and used a checkweight to confirm zero. It was off a bit so I cleaned the trays, moved it on the counter top and ensured it was level, which eventually brought me to zero:

I started weight sorting the 1x (cleaned) Lapua brass:

For this experiment, all I needed were 10 cases. So, while I would usually just group cases within a grain (for example, 179.00 - 179.98), I had some groupings with 10 case of the same weight:

Here's the group from the 150 that were way out of weight, either really low or high from the grouping shown above. These culls will be used for foulers, seating depth cases, etc., but not for any long range work.

Here are the 10 cases for the 1x testing:

I did the same for the Sierra 142gr Match Kings:

I need 30 bullets for for the testing, so I have to cross weights a bit. This is for velocity testing so I'm not too worried about any accuracy issues a grain may introduce. These weights let me load 10 each for two rounds (141.94 & 141.96) and 9 for the 3rd round (141.98) with one taken from the 141.96 pile for the last round. The hundredth of a grain is statistically insignificant for velocity testing.

I previously weighed out each round using the Ohaus, so I did it again for this testing - 41.9grns of H4350. This picture shows it with a charge that is a single kernel too high, dump a kernel and re-weigh.

I loaded up 10 rounds of the virgin Lapua (I had to use two differing weights as I couldn't segregate 10 of the exact same weight) and 10 rounds of the 1x Lapua:

I also took 10rds of uncleaned 1x and loaded them up. I didn't do a thing to them but make sure they weren't fouled. So, I loaded 30 rounds of the 142gr SMKs using 41.9grns of H4350 seated to 2.2705:

 

[Defender3]

I took the 30 loaded rounds out Saturday to Quantico to test the virgin Lapua's neck tension against 1x to see if there was an effect on velocity. In retrospect, I should have also payed attention to accuracy, but I was the OIC/RSO and took a quick break to get the rounds downrange.

As a reminder, the contestants were:

1x Lapua brass, not cleaned or processed, and with a neck diameter of 0.2980,

Virgin Lapua Brass with a neck diameter of 0.2905 and,

1x Lapua brass wet tumbled with a neck diameter of 0.2970. I thought it strange that both lots of 1x did not have the same neck diameter as they were fired in the same barrel, but I measured multiple rounds and they were consistent, the untumbled brass was a skosh larger.

I weighed and segregated each piece of brass (except for the uncleaned) and the bullets. Each was loaded with a F210M and with 41.9grs of H4350 (individually weighed) and loaded to a BTO of 2.2705.

From the 600y line. I was shooting the three Shoot n Sees on lane 7, which is the third target from the left.

I shot 5 rounds of factory Bergers to heat up the barrel and to ensure the Labradar was picking up each shot. I then fired the rounds in 10-shot strings to get the rounds out versus testing group size. I used previous DOPE and fired the strings with about 5 minutes in-between to cool the barrel.

Here are the results. I did have issues capturing some of the shots due to shooters around me, but I think there should be enough here to make some determinations.

Here are the targets - again, don't read into them as I touched off the shot when I saw the orange center - I should have taken more time. If we consider I used the same technique (or lack thereof) each time, the targets are telling me there could be more consistency with the 1x fire formed brass than the tighter necks on the virgin Lapua.

1x not cleaned:

Virgin Lapua:

1x wet tumbled:

Okay, I'm out for business travel to Kosovo of all places. I'll check in when I can and if all this was too much, I calm down.

I know that this has been asked and answered before, but how temp stable are you finding the RL16?

I have run the same load of Rl16 (41.4gr in Peterson SRP 6.5 Brass, CCI450, 140 ELDM) from 22 to 104 degrees and havn't seen more than 20-25 fps difference and no pressure. Getting 2835fps out of a 23.5" Bartlein suppressed. Just pay attention to the throat when cleaning, the carbon ring will appear.

Thanks. Good info. I run suppressed now with my .260 and H4350. I’ve had one carbon ring so far at about 1000 rounds and have more than 2000 since then. I’m keeping an eye out for it again.

Regarding suppressor use with RL16. I’ve heard that it runs dirty. How often do you have to clean your suppressor to keep cakes and flakes from falling down into the chamber?

 

[260284]

I am running my 6.5 with a brake for matches, but I did soak my 30P-1 with CLR for a week and got it almost down to new weight. Most of the rounds through it were XBR8208, CFE223, H4350, and 4451. I have a little over 1000 rounds of Rl16 through it now. I scrubbed my throat with CLR every 250-300 rounds after I got a carbon ring.

I am going to run some Rl16 in my 22BR and I shoot it suppressed most of the time. I loaded 10 with 32 grains under the 88gr ELDM and got over 3100fps and a SD of 3. Going to try .2 increments from 31 to 32 and see what it is like.

Here is most of the more complete data from the old site, organized by barrel length. I have edited it to a fairly standard format. I did not include ES/SD, COAL, or group size. I don't think they're important as your COAL limitations will be different from the next guy (and it's more work

). I did include jump/jam info because that is pertinent and useful to everyone. You're welcome.

Any reason everyone seems to use h4350 instead do imr 4350? I have tons of imr4350 and h4831. Just getting ready to get into the 260

Where do you guys find Remington brand 260 brass, it seems to be scarce.

It was scarce even back in 2014 when those posts were made. I use Prime branded Norma brass because I have it after shooting a few hundred rounds of their factory stuff. Great brass! Or just break down and buy Lapua brass. It’s worth it and has been shown over and over to be a better value over the long haul. When you can get 20-30 reloads on them, the cost per use is $0.04-0.05 per round. Cheaper by far than the bullets.

 

[Rem700ADL]

Thanks for the reply.

 

[lash]

Or, an option is to buy a couple hundred rounds of factory Remington .260 and blow through that to get the brass. Problem is, I don’t know if any good Remington .260 loads that aren’t just basic hunting loads and then do you want to waste barrel life on something mediocre?

My opinion only. Somewhat biased by my disgust at Remington for abandoning the round.

 

[Steel head]

Remington? Meh.
Lapua is excellent
Norma is ok.
I personally like necking up Winchester 243 brass.

You could shoot FGMM 142, load is good, brass is meh.

Prime or Berger loads should give good brass.

Look at what Remington did to the PSR project.
How could they be expected of seeing the true magic if the 260.

I couldn’t agree more. Remington’s history is full of great engineering concepts and pioneering rounds, negated by marketing milk toasts and lack of executive vision. And that is my completely sanitized and clean, running for office version of my view.

Don’t even get me started on the .357 Maximum!...

 

[Rem700ADL]

My chamber has a .295 neck. With Remington brass my loaded rounds show .290 with a 142 gr. SMK.
I was hoping to stay away from turning necks if possible. What could I expect with Lapua brass, I never had
the chance to try any. Getting ready to replace the worn out Remington cases.

 

[260284]

Peterson makes really good brass too. The new Prime 6.5 is loaded in Peterson.

 

[Badfinger]

Side Note on reloading: I've have been using Lapua brass for 99% of my shooting and recently became discouraged with extremely tight primer pockets using Federal match primers. I switched to (yes believe it or not) Starline brass and and winchester primers and it shoots just as well as Lapua but much much less expensive. #104.00 vs $69.00 per hundred. I'm still getting one hole groups of .400 or better! I don't know about longevity as I've only loaded it twice.

Call Remington or Nosler or Federal

I’d pass on all of those.

I have been shooting 260 rem since 98 when you can’t find brass you use what you can find and be happy to find it

I found this forum about 2 months ago looking for loads for my new 260 long range rifle and reading your post have been very helpful and I would like to thank everyone

That’s why I started necking up Winchester 243 brass
Easy to get
Cheap
Better than Remington or federal brass.

I tried Nosler.
Not impressed with it as well.

What type of 260 are you shooting

 

[TxWelder35]

Savage model 12 LRP 26" factory barrel

I've settled on the following load
Lapua LRP brass
Cci br2
41.0gr h4350
Lapua secnar-L 136gr
2850 FPS suppressed

The factory Berger 136gr ammo shoots really well in my rifle at around 3/4 moa. So I wanted to match the velocity of the factory stuff so I can go back and forth inbetween factory and box ammo if necessary with no dope change.

Only difference is I'm running a longer COAL. Im at around 2.875, reloads are consistently 1/2 moa out to 800. When I miss at 800 it's all wind, not vertical

 

[Rem700ADL]

What type of 260 are you shooting

Its a Rem. 40XC with a Chanlynn 1-8 twist SS barrel. It has a 6.5-08 chamber with a .295 neck.
All the brass I have fired in it so far was Remington, because of the thinner neck diameter.
I don't want to get into turning necks with other brands of brass.

For what it’s worth, I found that the Prime head stamped Norma brass I'm currently using has thin necks that hold up really well. I like that and also do not want to get into turning necks. If you can get a batch of once-fired of this brass, it is well worth the 40 cents or so each you’ll pay.

 

[Rem700ADL]

I'll will try to locate some of the Prime once fired. Appreciate the info.
