[QUOTE="WildBillG, post: 2224931, member: 106952"] Earlier this spring I built a 338 RUM on a Mk V action. After some testing I found 2 loads to try. I am shooting the 300Berger EOL out of a 30 inch Jury barrel. My 2 loads that look good are 91.5grns of N570 and 97.0grns of RL 33. Both are seated at 3.915 with Fed 215 primers and Bertram brass. The N570 gives me 2844 with an ES of 6and SD of 3. RL 33 gives me 2888 and an ES of 10 and an SD of 4.4. N570 gave me .527 and RL 33 >392. Both really good which load would you guys choose given the info.. One other thing when I tested loads I used Fed 215s but I think I used Rem 9.5 when I chrono'd will that change velocity much.
