I am looking for help 260 load. The rifle is a JP LRP 260 with a 22 inch barrel. It shoots 109's like crazy but want to try 123 SMK or Lapuas. Have also looked at 130gr Bergers. Would like to get a velocity of around 2850 to 2900. Thanks for any help.

Re: Suggested 260 loads
Yoshi, welcome to the hide.
There are several threads containing 260 rem loads.
You failed to mention your barrel's twist rate.

Looking for the same info. Going to be using rem brass, H4350 and the 123 sierras.

Re: Suggested 260 loads
45-46gr H4350, or 44-44.5gr RL17 should get you the velocities you want with 123s.
Personally, my 120/123 load de'jour is 39.3gr Varget. It produces slower velocities than either of the above powders but is stupidly accurate and very easy to load for.
What I mean by that is it bugholes in two rifles (22" 9 twist Remington barrel, 26" 8 twist Criterion), two different bullets (120 Nosler BT and 123gr A-Max), three different types of brass (RP, Lapua, Nosler), and two different types of primer (CCI-200 & WLR).
With 123s I get 2936fps from the 26" 8 twist barrel, while with 120s I get 2800fps from the 22" 9 twist barrel. Of course these are bolt guns...your gas gun will likely be different.

Re: Suggested 260 loads
Well that's enlightening. I had considered Varget faster than ideal, but now I may have to revise my thinking.

Re: Suggested 260 loads
Varget provides less velocity than H4350 (50-100fps in my experience with 123 and 140gr bullets) but has proven to be very accurate.

BU's experience close to mine I can't get the velocity before pressure shuts me down. My accuracy very good but not steller in SakoTRG 260, H4350 for me with the 123.

Re: Suggested 260 loads
I worked up some loads this last week to try out today. I shot loads with Varget, 4064, and 4350. The Varget loads performed the best out of the three for accuracy but I did not chrono them. The best load was the 120g AMAX with 38g Varget. These were factory Remington brass being fireformed in my AI chamber.
I did have one load using 120 Nosler BT and 42g H4350 that was very close to the AMAX load.
