[QUOTE="Autorotate, post: 412908, member: 8073"] WC Due to the many variants of the 338 Lapua Improved, you'll need to get a hold of your reamer print and post it, or get a hold of a once fired case from a chamber made with that reamer, and measure your case volume. When you crawl behind a rifle with 100+ grains of Retumbo pushing a 300 grain bullet....you get the point. Best to know your getting data that matches, or is close to your chamber, and then you can find out what works best for you. FWIW-2820 fps with a 28" 9.8 twist Brux fireforming loads with a 338 LMAI easily held sub MOA for me at 966, 1033, and 1231 yds. And someone told me that .818 G1 works well with them too:)......sure enough it did. No nose slump for me at this twist/velocity level. [/QUOTE]
