[QUOTE="Darryl Cassel, post: 255, member: 34"] Hello Peter If your just talking about a standard case such as the 338 win. Mag. it would be hard to start out a 300 Gr bullet with enough velocity and retained energy to do what we do with a large wildcat such as the 338/378 Weatherby IMP or the 338/416 Rigby IMP. If you run the ballistics on your computer, start the 338---300 gr out at 3250 and then run it 3310 (Which I have done with mine) and you will see a full 180 degree turn in ballistic numbers. When you have a case the size of the 416 Imp and shoot 122 Grs of powder down a 37" barrel it's a whole new ball game. You can't compare a 338 Win mag to what we shoot. My Oehler Balistics program shows that there are 3104 FP left at 1000 yards and 1197 FP at 2000 yds which is plenty of energy especially since I ran it at 3250 and not the 3310 that I can run the bullet. I'm not sure if you were just refering to any 338 or just the 338 Win mag. Anyway, for the 338 Win mag. the 300 gr bullet may not be the one to use. In our big boys, it is. Peter, just read your other post and you did mention the 338 Win Mag. Factory rifle. If it has the 10 twist it will stabilize the 300 gr bullet. The 338 Win mag is a good cartridge for shorter ranges and has killed many deer, elk and Bear. My 338/416 IMP has a 10 twist and does fine. keep your ranges shorter and you will do fine with the 338 even with a 250 or 300 gr bullet.
