[QUOTE="BryanLitz, post: 715141, member: 7848"] I've developed loads for several 300 Norma Mags and 230 grain Berger Hybrids. 3000 fps is pretty easy with no pressure in 26" barrels with H1000. Given the shortness of this cartridge, it's easy to run a long throat, seat the bullet long, and get the bullet out of the case while running comfortable mag length for a repeater. Can't really comment on barrel life, but I wouldn't expect much more than 1000-1200 rounds. It's a lot of powder. Oh, and inherent precision was awesome in both rifles. No apparent sensitivity to seating depth or powder charge. It's usually not so easy to get such easy precision with such a high ballistic performance round. As a piece of anecdotal information, I watched a 17 year old boy shoot a wild hog in Texas at over a mile with this round and the 230 Berger Hybrid. Hit on 3rd shot after bracketing the wind. Bullet passed straight thru behind head, lights out. If I were going to build a .30 cal for long range hunting this would be it for sure. Don't forget a muzzle brake. -Bryan [/QUOTE]
