Tac Report post Posted October 30, 2015 i have been reloading for a .338 and it just seams to have consistency issues it was grouping well initially but seems to shoot larger groups. i have been using 265 barnes and us 869 powder is this powder inconsistant? what are other guys using for this caliber? I have a second one that i shoot 300 gn target and us869 and it works well Share this post Link to post Share on other sites

Tac Report post Posted November 16, 2015 Tried Imr 4831 and 265 lrx not so good. Went to us869 and 265 lrx and shot 1/2 moa. I,m happy now! I fixed me and lightened up on holding the gun and it started going well. I must have been torquing the gun. Share this post Link to post Share on other sites
firstcoueswas80 Report post Posted November 16, 2015 Id think 4831 would be far too fast. Especially compared to 869. Share this post Link to post Share on other sites
shoottoshoot Report post Posted November 16, 2015 H1000 is what you want to use. Velocity and accuracy will stabilize unbelievably! I have some for sale if you're interested. Share this post Link to post Share on other sites
Camofreak Report post Posted November 17, 2015 How many grains of H1000 do you guys load up in those Lapuas? Share this post Link to post Share on other sites
huntermncb Report post Posted November 17, 2015 89 grains of h1000 would probably work great Share this post Link to post Share on other sites
shoottoshoot Report post Posted November 19, 2015 I load my 338 Lapua mag w/ 250gr scenar at 91.5gr. Depending on the velocity you want, I think 89-90 grains is a great place to start. Share this post Link to post Share on other sites
Becker Report post Posted November 19, 2015 Every gun is a little different. My edge max powder charge is 87.5 to 88. Just be careful and start low and work up. Share this post Link to post Share on other sites
GreyGhost85 Report post Posted November 19, 2015 My lapua likes 89 grains behind a 285 a max. For a lighter bullet, try a little more, a heavier bullet, try a little less Share this post Link to post Share on other sites
