[QUOTE="Black Diamond 408, post: 247153, member: 1563"] masterdiver, Yes the 375 cal. has the best case capacity to bore ratio of all. The 375 will out perform the 408 in some catagories as you seen from the testing done. Most 408's loaded with the 419grn bullet will see muzzle velocitys around 2800fps. The 375-408 cheytac version with 350gn bullets will see a muzzle velocity of 3100fps. I belive the tests that Dean Mc. was doing was a velocity more around 3000fps. The bullet BC they were testing was a 375cal .945 Cheytac solid. VS a 408cal .945BC 419gn solid. The added speed of the 375cal makes this a more impressive round. On top of that, any case improvments add to the potencial of the overall case design. In my opinon the 375 on the 408 case is the best for overal performance and barrel life. The 338 version is my favorite but the barrel life will be shorter over either the 375 or 408. Dave [/QUOTE]
