[QUOTE="ZSteinle, post: 689130, member: 10411"] quickload says 338 lapua mag with a 300 smk seated to 3.681 oal and volume of case occubied by bullet is 16.1 grain. Take it to 4" oal and volume occubied by bullet drops to 9 grains. But keeping pressure the same 60,000 psi you gain around 40fps by going to 4" oal. So not much. [/QUOTE]
