[QUOTE="Mysticplayer, post: 3516, member: 8947"] The big difference between the cases you mentioned will be recoil, muzzle blast, and throat erosion. The vel. difference would be 100fps or so. In fact, depending on barrel, each case could overlap the other for vel. vs accuracy. Bullet construction may also be an issue. These cases are overbore so gains are small for massive increases in powder. For hunting mid size game under 700yds with 140gr bullets, my choice would be the good old 7 Rem mag. This will be within 200fps of the others and field performance is negligible. If you plan on using heavier bullets, then the story changes. These big case magnums start to make sense when 160 and heavier VLD bullets are in mind. Of course, longer heavier barrels will also be needed to make them really work. This is the stuff for 1000yd type pokes. If you want a good walk around hunting rifle, even the 280 AI or 7X57AI are excellent choices. I like to keep impact vel. under 2800fps because of meat damage and bullets blowing up (not a fan of expensive premium bullets). Get an idea of the ranges you want to hunt, size of game, type of shots you will take and go from there. As long as you can get a (conventional)bullet into the boiler room at 1500fps or faster, you are going to need a knife. Good luck... Jerry [/QUOTE]
