H1000 Or Retumbo

Hi,

I would like to know what 338 Lapua owners prefer, H1000 or Retumbo for 300smk's? Everthing that I could find seems to favor H1000. Also, which powder is more temperature sensitive?

From what I have found on LRH and other sites, Retumbo seems to give better velocities than H1000. Look forward to hearing your suggestions.

Ray

    I am running 92gr H1000. I am getting about 1" Groups at 300 yards. Velocity is around 2750 out of a 26" tube as I recall.

    SES50,

    That says it all about H1000 in your gun. I can only hope mine does that well when I get it.

    My barrel is a Lilja 1-10 twist, *8 contour w/28 1/2 barrel + Muzzle Brake. I'm pretty sure H1000 is the way to go, but would like to hear about folks using the Retumbo. If all else fails...I will try both powders when I get the rifle.

    I'm just starting out on this, but I'm finding Retumbo better than H1000 in several of my barrels. In fact, if you want more H1000, I'll trade you. Just PM.

    Would you mind sharing a little more info about your loads with Retumbo? Velocity, ES, SD, etc. I would also like to find out how temp sensitive Retumbo is if you know.

    I already have a 8lb. keg but Thanks anyway

    What about RL25 and US869? Are many of you using either of these powders in your 338LM with the 300smk's?

    Not 338, but I have tried both in my 7mm STW. I can get higher velocities with the Retumbo than the H1000. If I continue to load up the H1000 attempting to get close to launching a 168 gr Sierra MK at 3200 fps as I get with the Retumbo, I start getting severely flattened primers and I get nervous about pushing any harder. The best velocity I can get with the H1000 is about 3080 fps.

    I assume the same relationship between the powders would exist in the 338.
