[QUOTE="mindcrime, post: 107116, member: 656"] Kirby is correct, I have the original .416 Rigby (elephant rifle) chambering, and the case is .176" longer than the Lapua case. I have 200 pieces of Norma brass that I have been loading to MAX loads according to the Barnes manual with no pressure signs at all (soft Federal 215M primers too!). I was shooting the 325gr. X bullets at 2875fps with 110grs. of RL-22 (25" barrel), however Barnes has discontinued the 325gr.
