Re: 260 Loads Only

Thanks fellas. Will PM if that the reamer I decide on. Still waiting on stock before I get my action barreled up.

And Snafu, make sure you give all details on build as well as the results of shooting that perticular cartridge/combo.

Re: 260 Loads Only

My .260 load:

-FL sized and trimmed Rem. brass
-139 Scenar
-BR2 primer
-46.8gr. H4831SC
-Seated 2.300" from base to ogive

Chrono'd at 2920 +/- 5 fps out of a 26" Bartlein. I've pushed this load past 3000 fps easily but accuracy declines.

Re: 260 Loads Only

Junk Savage with a CBI 28" bull barrel 1:8. Running 7-08 Win brass with BR-2s.

100gr NBT at 2.790" 43.5gr IMR 4064 3400+fps

120 Amax at Same die setting as 140 Amax 45.0gr H4350 3003fps.

Accuracy with these 2 loads is stupid tight.

Had issues with 140gr BTHPs. Bad lot of bullets. Sent them in and they gave me 140 Amax for replacement. I need to bump up the charge weight to 43.something and see what happens. I am willing to go with H4831 as I have it for a M7 260 and 140gr core-lokts but 1 powder for the 120 and 140 would be nice.

Velocity? Pressure signs?

39.0-39.3gr Varget shoots well for me with the 123 A-Max, but velocities are a fuzz low around 2900fps.

Re: 260 Loads Only

RP brass - 3 firings
CCI 200
Varget 36.0
142 SMK moly
2565fps

several 1/2" groups at 200 yards 35.4-36.0 yield 1MOA or better.

Rem 700LTR action with AAC brand 24" .260 barrel.

On velocity, I hit a wall. 38.0-39.0 gr varget all yield 2670-2700fps - it will get no faster.

I use Varget in .308 and heavy .223 loads, so was hoping to do well with it in .260 even though the velocity is not there.

I shoot the 178AMAX in .308 in my Noveske AR10 and get 2450fps with the M118LR clone load - so this .260 load will have the same velocity at 1200 yards as the .308 load at 1000 yards - with 5 grains less Varget!

Gotta get some H4350 and chase that velocity in the .260.

 

[colt933]

Re: 260 Loads Only

Since my barrel is nitrided, I think I'm going to skip the moly and hopefully make it up to 2750 with Varget.

I would skip the moly even if your barrel wasn't nitrided.

Do try H4350. My velocities with varget were like yours. H4350 will do more with probably less peak pressure.

Re: 260 Loads Only

I'm hopefully getting my .260 barrell soon. I've got H4350, Lapua 139g scenars, BR2's and Lapua .260 brass.

What is a recommended starting/max for this brass/bullet with this powder? Lapua and Hodgen neither call out this exact permutation, but I'm sure one of the powders Lapua specifies has similar characteristics... I was thinking of starting at 39g and working up...

Re: 260 Loads Only

For those of you running H4831SC and 140gr bullets, how are you handling compression?

I loaded up 3 today with 46.0gr 4831SC in virgin but FL sized Lapua brass with 140 AMax to 2.895" OAL, which is about .005" jump in my barrel and produced 2762fps last week and stupidly low variation (ES 6/SD 3). Shot well, but I'm hoping for more speed.

Loaded up 3 more at 46.5gr and the OAL went to 2.905 without changing the seating die; at 47.0gr it was 2.915. Can't help but think the compression is pushing the bullet out of the neck a bit...wondering if a drop tube or using fire-formed brass (I've found 1x Lapua has 0.7gr more capacity than virgin) would help...because tapping the case before seating ain't doing it.

 

[Hondo64d]

Re: 260 Loads Only

I run H4831 in my .260s and of course get compression too, but have not noticed that it is affecting my COAL. I use a 6" drop tube. So far, H4831 is my favorite in the .260, giving me the best accuracy.

Re: 260 Loads Only

just wanted to give people the heads up...

i was necking down once fired 308 brass to 260, but the necks were so thick i had to turn them down requiring a not so cheep tool...

i tried some privi 243 brass, 1 pass in a lee collet neck die, and they are good to go... no lube, no extra work other then flash hole debur and chamfer..

and the best part is new privi 243 brass is the cost of 1x 308.. 100 for 25$ at grafs...

i just ordered another 100 bag..

Re: 260 Loads Only

Here's a five shot group from a load I tried on Saturday. Seating depth shown on target includes Sinclair "hex nut" bullet comparitor. My rifle has an extended box so OAL is about 2.915" which puts the 130gr VLD about .035" from the lands.

Re: 260 Loads Only

Not a varmint load, but would be a great choice if concerned about not ruining pelt.

140gr Nosler bthp
Remington case
CCI 200 lg rifle primer
43.5gr XMR4350
2.8375 oal

I use the Nosler comp bullet because I also load for 6.5x55 and this bullet has it ogive beginning further forward than the Sierra 140SMK and this is a plus for my 6.5x55.

Rem & Nosler cases (New 260 Lapua cases being prepped as we speak!)

Re: 260 Loads Only

jb,
I have had good luck with H4350. For the charge weight I would suggest starting at 40-41ish grains and working your way up. If you have access to 300 yrds start at 40 and load in .3 grain increments up till 46.0 grains. You should check your brass as you are shooting to notice any signs of over pressure. You will have to mark the shots each time to establish where the accuracy nodes are for your rifle. It is usually pretty clear what your rifle likes. This is how I test my rifle for loads and has worked well for me. A chronograph is nice to have while doing this. Also the bergers(vlds)aren't known to be jump tolerant. I have found for my rifle that .010 jump works well. Since I don't know the specs on your rifle or reamer this is just a starting point. The aics mags will let you seat out a fair distance. From what I have seen 2.910ish. If your chamber is a match/tac match you will be into the lands before you run out of mag.

good luck

Rthur

Re: 260 Loads Only

Hey guys I need some advice. Just got my AIAW in 260. Running a 24 inch barrel. I haven't been able to pick up any H4350 yet. So I worked up a load with 36.5 grains of varget with 142 SMK. It is running 2640 fps. The damn thing shoots lights out. Last week I shot around a 1/2 inch 5 shot group at 200 yards. I am able to keep 10 shot around 1/2 min @ 100 easily. My issue is it is taking almost 36.5 min @ 1000. My question is. Is the extra velocity gained with H 4350 worth scrapping this load? Will the velocity gain show up noticably in my dope? This is my first 260. Any advice is appreciated.

Obviously you won't know what to think until you do a load workup using H4350. My AW with a 24" Bartlein barrel favors 41.5 and 43 as two accuracy nodes with H4350 and will do what yours has with Varget, but, at a significantly faster velocity.

Lets say your barrel/gun combination doesn't perform with H4350 (unlikely). At that point you have a decision to make. Myself, I'd go with precision/accuracy.

Good luck.

 

[BoilerUP]

Re: 260 Loads Only

I would think there's one higher node than 36.5gr with Varget and a 140-class bullet around 38 grains...should get you near 2750fps.

FWIW, I get great accuracy with 39.3gr Varget and a 123 A-Max at 2930fps...which should shoot about 5MOA flatter @ 1000 with just slightly less drift.

 

[Smith44699]

Re: 260 Loads Only

Thanks guys. I will pick up some h4350 this afternoon. Hopefully have some time to work up some loads. I will also start taking my varget up a little as well. I will update when finished. Just hope it starts warming up a little. I had 12 early this morning. Got 14 now.

 

[Smith44699]

Re: 260 Loads Only

Well just finished working up new load with h4350. 43 gr was really good 10 rounds at 1/2 moa. 44 gr first 7 was 1/4 moa with the last 3 bringing it to about 3/8. I think this was my fault due to heat from my suppressor. I am using 142 SMK nosler brass win large rifle primers. Zero pressure signs. Thanks KIMO and BoilerUp. You guys gave me some incentive to go out and get something better. Velocity is unknown. My chrony is at a buddies house.

Re: 260 Loads Only

Ok fellows. Just an update on my load for my 24 inch AW. I was at the range Monday getting some drops. Worked my way out to 725. Longest I had there. My load is 44 gr h4350, 142 SMK, nosler brass, and Winchester LR primers. I am 25 thousandths of lands. I shot a damn nice 1/4 inch group at 200 yards. That was on twice fired brass. Zero pressure signs. Connected with some clay birds at 600. I was having a great day. I shot around 60 rounds of the twice fired brass. Well when I got to the third fired brass. I started to get pressure signs. Not real bad at first. But there none the less. To top it off it was raining toward the end of my session. I may have gotten some humidity on my cases. I started to have some blow by around my primers at the end. I am tossing the nosler brass for sure. Just wanted to give an update. IMO nosler brass is not worth it. I will stick with lapua. Hell Remington brass will probably do better with the pressures. I am just glad I wasn't in a match.
