Loads for .260 /.243/ 6.5x47/6.5 Creedmoor

[Rover31]

Re: Loads for .260 /.243/ 6.5x47/6.5 Creedmoor

DPMS 260 25inch barrel (yes it is cut down with a muzzle brake)
Win 7/08 brass resized flash hole deburred
CCI LR
140g Nosler Match
43g H4350

yes it is over the max charge but very accurate with zero pressure signs.
I had another very accurate node at 41.5g

These are all loaded to max mag length using C Products mags. These mags allow a slightly longer overall length.
another FYI the nolser 140g match bullet is the short one of the 140g 6.5 as far as I can tell. the Hornady Amax and the Sierra SMK and the JLK bullets are longer overall.
I tried H4831sc and it looked to be working up good but it just never achieved the grouping that the H4350 did.I also tried H1000 as it is listed in the manuals as a high velocity powder. It was never able to achieve the groups either.
Enjoy!

Re: Loads for .260 /.243/ 6.5x47/6.5 Creedmoor

Rover31 what OAL length are you loading at? 43 gr of 4350 in my dpms is starting to show signs of pressure. Primers look slightly cratered and a swipe on the tops it looks like. Varget shot well at lower charges but only tested at 100yds. Other than running AMAX 140 bullets our setups look similar for similar gas guns.

Re: Loads for .260 /.243/ 6.5x47/6.5 Creedmoor

I waited for DPMS top build either a 6.5 Creedmoor, or 260 Remington for a long time. Eventually they obviously came out with one. The reason it took them so long is that they had an issue with primers popping out. So, for whatever reason caused the primer issue, I would urge you to keep in mind that primer problems was the reason release of these cartridges was delayed so long by DPMS....at least that is what they told me, and why I eventually bought a 308.

The primer issue would indicate that primer problems shouldn't be used as the only, or primary over pressure indicator. Although useful, I think that primer problems in the DPMS guns isn't as reliable an indicator as it would be in gas operated rifles that didn't originally have issues with blown primers.

I've got a stock R700 SPS Varmint .243 that I have been shooting 87 VLD with IMR 4064. I am going to try some moly 105 Amax with IMR 4064. Does anyone have any data for this setup?

Thanks

Re: Loads for .260 /.243/ 6.5x47/6.5 Creedmoor

I'm about to receive my 4th rifle that is chambered in 6.5x47. It is a lighter weight hunting only setup. I normally run 130/140 VLD's and 4350 in all my other rifles. However, with this rifle I'm going to try some 123 A-max's and Varget. I've been wanting to try the A-max for hunting and I have a extra 5 pounds of Varget that I'm not using for anything. This will be inside 600yds hunting rifle for deer, coyotes, and various other critters.

Can anyone give me any reccomendations on this combo? Mainly on seating depth of the A-max. On all my other rifles, the Bergers like to be in the lands anywhere from .003"-.009". Are the A-max's the same way or do they typically like a jump? Gonna start around 36.5gr of Varget and work up from there.

Re: Loads for .260 /.243/ 6.5x47/6.5 Creedmoor

Trevor,
I tried 162 amax's in my 7mm STW, liked to jump .500".
This bullet also went through 3/8" AR 400 plate at 200 yards, clean hole. Another guy with me shooting a stw, and some white tipped bullet, not sure what make, and his barely pocked the target.

I don't think you'll be happy with the amax as a hunting round. Pass through deer, and won't be violent enough on a coyote. But I'm sure you know what you want.

[Unknown]

Re: Loads for .260 /.243/ 6.5x47/6.5 Creedmoor

Donovan,
I was considering the 6.5 CM, but as brass for it is only available from one source, I went with the 260 Rem. Either cartridge is great, as ballistically, they are about as close to twins in performance as is possible. I just wanted more diversity in brass acquisition. About 6 months after I completed my build, Lapua announced that they were going to be selling brass. So, with Lapua brass, I think I really guessed right.

I just wish I could rightly claim that I planned on using the Lapua brass all along.

Re: Loads for .260 /.243/ 6.5x47/6.5 Creedmoor

If the worst group is .620 inch, I agree with your assessment on load development....as long as you aren't a bench rest shooter. There are lots of people who would be pretty happy with the BEST group being .620 inch.

Shooting the 6.5 Creedmoor round for 3 years and have seen no reason to change from the factory load data.

In a properly plumbed rifle the Hornady load will hold 1/3 MOA and better @100m.

With proper reload technique and the 140 A-Max/41.5 H-4350 load,brass should last 10x.

Re: Loads for .260 /.243/ 6.5x47/6.5 Creedmoor

I suppose it could be the cooler weather causing the reduction in velocity. I notice the same thing with my 300 win mag and IMR 4350. During cooler weather, velocity is 2960 FPS with a 190 Sierra match king. In summer, I don't shoot the ammo as velocity gets hovering around 3000 FPS.

It may be safe, but I have other rifles I can shoot, and I don't have to think about the possibility of blowing primers or cases.

Excess pressure always finds a way out, and it is usually expensive, inconvenient, dangerous, or any combination of the three.

Re: Loads for .260 /.243/ 6.5x47/6.5 Creedmoor

My current Creedmoor load is:
140 Amax

No sign of pressure what so ever.

I'm excited to be able to shoot the Hornady BTHP 140's when I need to start chasing my throat and run out of mag length with the Amax.

Re: Loads for .260

Was going to the range tomorrow. Does anyone have a good load for 6.5 x 47 lapua - 142 SMKs with either H4350, RL15 or RL17?

Any help would be appreciated.

[Unknown]

Re: Loads for .260

One way to find a good starting point is to review this thread and find out what other people have had success with using the same components you are planning on using. I did that with 308 and my final load ended up only .2 grains from the average I got.

To even out the curve, I threw out the high and low loads, then averaged all the other loads using the same powder, and bullet I wanted to use. The average load I got was really a good one, and I found that my rifle's preference was a load that was only .2 grains away from the average.

I was lucky to find about 20 different loads to use for my average, so I think the size of my statistical sample helped me out a great deal. It is a good way to start out.

I would guess its for a .260. I don't think you can fit that much 4350 in a creed case and I know you can't fit it in a 6.5x47 case. I'm crunching the hell out of it at 42.5 grains.

Re: Loads for .260 /.243/ 6.5x47/6.5 Creedmoor

I finally got some 123 Amax's for my newest 6.5x47 hunting rifle. Im going to load Varget with them. Anyone tired this combo yet? It's a Krieger #5 @ 22" barrel and I've ran some 130 VLD's/Varget through it with excellent accuracy (smallest group I've ever fired to date) at around 2,800fps. Didnt have any pressure issues. I'm hoping I can get the 123's closer to 2,850+ fps with a decent dose of Varget, but not ride the pressure limits.

Re: Loads for .260

2750 fps huh, what velocity are people getting with the factory Creedmoor 140 ammo? I get 2830ish fps (Oehler) and so I dump in the powder until I match that velocity, thus my 42.6 grns of H4350. I've found the factory load to be the most accurate bullet/powder combination so I've tried to match that.

I'm using a 26" barrel

Re: Loads for .260

I wish more manufacturers would post the info for 260 Remington as is done for the 6.5 Creedmoor. But then, the manufacturers are probably thinking we wouldn't buy their ammo.

I think the goodwill, and ability to purchase match grade ammo that will work in your rifle if you run out of handloads would be worth posting the info though.

It really depends on the barrel/length. I know factory load is around 41.5 for 140 A-MAX. It's right on the box.

 

[Unknown]

Re: Loads for .260

Gau17,
If I were trying to match a factory load, I would probably try the same thing you are doing. The potential problem with that is not knowing whether the load I come up with will be over or under pressure because I don't have pressure reading devices. Some rifles have faster, or slower barrels even when shooting factory ammo. So if I have a slow barrel and use my idea of putting in enough powder to match factory velocity, I might end up going over pressure.

I use a chrono, and for most of us mere mortals, that is the best we can do to try and get close to factory ammo. But without a proper pressure barrel and equipment, I don't have any idea what my pressures are.

I had to return a factory made rifle because it had a horribly short throat. I'm sure that the reamer just wore out prematurely, but the rifle showed horrible overpressure signs with factory ammo. Well...that and rounds sticking in the throat, and when I could finally get unfired rounds out of the chamber, they would come out with the lands clearly engraved onto the ogive. I mention this because of my earlier writing about pressure issues.

 

[ctressler]

Re: Loads for .260

I've read a few posts from people that opened a factory round and even though the box indicated 41.5 grns, they discovered it was more than 42 grns. I Think the 41.5 is a suggested starting point. The boxes I have say the velocity is 2820, but the Hornady website says 2710, using a 24" barrel.

With regard to pressure, since I'm matching the same velocity shot from the same barrel, the pressures should be the same if I use the same powder and primer, I think.

 

[Unknown]

Re: Loads for .260

I think the logic of matching your velocity to factory is sound. The problem is that because all rifles are a bit different, if the factory tests with a fast barrel, and you have a slow one pressures can be much different.

Add to that, the idea that the powder charges on the box don't match what is in the case, and things can be really confusing for folks like us trying to match up.

It would be interesting to find out what Hornady says about the difference between published, and actual powder charges. I could easily understand a couple tenths due to differences in humidity and hence moisture, but half a grain is quite a difference.

For my rifle, Rel 17 liked the Fed 205m better than my favorite CCI 450 @ H4350. I can pop my 15"x27" LV steel sil out to 1100 yds with this load.

I may have screwed the pooch. I wanted the rifle to balance better so I had 1.5" taken off the back end of the barrel and had the action mid-turned, loosing a total of 6.5 oz.

41.3 gr = 2851 fps, 28 es, no sd, 1.38 MOA for 4-shots

I'm planning on fine tuning the 140 MB and Hunter load since the bullets are cheap, are only .25 less BC than the 140 VLD and Hunter is a dream to "throw" from my Harrells meter; cheap too.

Hornady Brass

2.800" OAL
42.5gr of Hybrid 100V
2900fps

seems a little fast too me, the book says 42.8gr should yield ~2800fps. I measured the charge for every bullet to be precise. I saw no pressure signs on the brass but I still might bring it down a bit and retest it. It was very accurate

Hornady Brass
140gr Berger VLD
2.800" OAL
42.5gr of Hybrid 100V
2853fps

This one is also a tad faster than the book says but still no pressure signs. This one was extremely accurately, putting 8/10 into a <1in hole at 200 yards. The other two were flyers due to me.

Anyone else have any experience with Hybrid 100v? So far i really like it.

wouldn't you keep a box or two of factory loads to fire as reference shots to compare with your own loads?

 

[Unknown]

Re: Loads for .260

The reasons stated in the previous posting are some of the primary reasons that matching up to a factory cartridge is almost impossible, unless the manufacturer does like Hornady did with the 6.5 Creedmoor and print the recipe for the load on the box.

Most ammo manufacturers use bulk powders that are usually only available to them. The powders will be similar to powders hand-loaders can purchase, but are rarely the same powder.

Hand-loaders even have to watch out for variations from lot to lot when using the same powder.

I'm not sure if it is a deliberate attempt to prevent hand-loaders from being too easily able to duplicate what the manufacturers make, or if it is a liability concern that causes manufacturers to not print the recipe. In either case, the almighty dollar is at the root of it.

It would be wonderful if more manufacturers put the exact recipe on the box. I suspect that if they did so, more people would buy ammo to see how it shoots, then try to match it.

Hand-loaders will load in any case. For me though, I don't buy factory ammo because it isn't cost effective for me to do so. However, if the recipe was on the box, I would buy lots of boxes just to see how it shoots, because then I might just find a load I hadn't thought of...otherwise, I just wouldn't buy their ammo.

Re: Loads for .260

I'm also using the Win 7-08 cases necked down, no turn. I haven't had any issues with donuts, or excessive neck thickness. However, when the 350 cases I originally purchased eventually die, I'll probably go with some Lapua just to see if the tougher cases allow me to get more performance without any pressure issues.

But, I'm running a 27 inch Obermeyer barrel with a brake on it, and that gives me higher velocities to begin with. My 142 grain loads run in the 2900 fps range with no pressure signs, but I'm using H4350. I'm thinking of switching to try IMR4350 because that is what I load in my 300 win mag, and it would be nice to not have two powders that are so darned close. Of course, I could always try the H4350 in the 300 and accomplish the same thing.

I doubt you will, as the Lapua I have been using have noticeably less case capacity. When trying H4831SC, I can't even fit enough in the case to match many of the loads posted here. However, I did buy them when they first came out and had necks thick enough I had to turn them all, so the entire case might be thicker than what they're putting out now. My Win 7-08 brass has been doing very well, so much better than the RP 260, and I don't think I'll bother with the expense of the Lapua again.

Re: Loads for .260

For you guys using a .289 bushing, are you still using the expander ball? Do you find your loads are more consistent using the expander ball (more consistent neck tension)? If I don't use the expander with a .289 bushing, the tension is enough that the seating stem digs into the bullet jacket. Was wondering if it would be worth it to use a .290 without the ball. I tried a .291 but doesn't leave enough tension.

Re: Loads for .260

I was prompted to try a slightly tighter bushing that gave more than .001" tension. Tried the two bushings that would give .002" and .003". The .002" was the best of the three. Might be worth testing in your own rifle.
