[QUOTE="SLEDGE HAMMER, post: 921185, member: 76860"] Yeah thats good to have someone with experience. What I cant work out is if the 338-378 is so close to the Excalibur and the Weatherby / Norma brass is so soft why do I keep reading that with a (say) 34'' barrel its not hard to get 3100 fps out of a 338-378 with a 300 with out extraction problems. And the Excalibur has around 8 grns more case capacity,Kirby wrote once when he was developing the 338 Raptor that the Jamison brass was fine at 61000-62000 psi but had extraction problems when he got to 65000. Can you tell us what velocities and with what projectile weight etc that you started to have extraction trouble, Thanks [/QUOTE]
