338x378 wby mag/ RL33 ?

[backwoods83]

Anyone have any data for the 338x378wby with 300grn Smk's 4.065" oal for a .120" jump?

I'm running mine at an oal of 3.8 with 110 grains of RL33 behind the 300 smk. I went up to 112 during load developement with no pressure signs. 110 grains yields 2895 fps in my 26 inch barrel. Hope this helps

What kind of accuracy are you getting? What was the velocity with 112grns? Accumark? Bedded? Trigger work? Thanks.

I didn't chrono the 112 loads. Its an accumark bedded in factory stock with timney trigger. It will hold .75moa to 1000 if I do my part. I have taken it to 1400 with good results usually around 1moa. This load took a handful of deer this year from 240 yards to 876 yards with great results.

Thanks for the info, I skim bedded mine, also an accumark, with devcon, and tuned on the trigger for about 2hrs and ended up at 21.5oz pull, real crisp to. Also devconed the base. Now I'm waiting for it to smack me in the face with that little tiny thing weatherby calls a muzzle brake!
