Good afternoon, Gentlemen. Thank you all for the responses. The cartridge is a 7mm-300 Wby with a 27" 8-twist. I originally built this rifle for ELR purposes and am switching it over to just a hunting rifle. Given the case size, I would prefer to stay 165gr and heavier, otherwise managing velocities becomes problematic. As for bullet preferences, I try to steer away from Bergers, I've just had too many pass through an animal with minimal expansion. A-frames, Partitions, even Accubonds and Ballistic Tips have been very successful.
Thank you again
Michael
