338 Lapua/ 300gr SMK

I'm trying to work up an accurate load with my 338 Lapua with a 30" barrel for an upcoming elk hunt. I've tried H1000 so far with 1" 3shot groups at 100yds. Anybody know of a better powder to use or have any insight on this cartridge/ bullet combo? I've heard that Retumbo works pretty good in another members rifle, looking for any and all advice.

I use RL25 and Retumbo.

I also keep the velocity at 2850 to 2900 (less than maximum velocity I can achieve).

Re: 338 Lapua/ 300gr SMK

Thanks for the info. If I may ask, what length and contour is your barrel? Also what kind of accuracy are you achieving with your rifle?
My barrel is a #5 contour and fluted, heats up pretty quick with just a few shots. Nice to carry but 3 shot groups are about it unless you have lotsa time. Took 2hrs to shoot 4 groups.
Thanks again,

I have had good luck with H1000 in my 338 Yogi (338 Lapua Mag IMP) and as Dave suggested RL25 is a good one you may want to try Retumbo also. What bullet are you shooting? I have shoot 8.5 inches with my gun at 1000 Yards that was 10 shots. The barrel is a 34 inch lilja

If you think something is not possible move out of the way so the ones that are doing it can
