[QUOTE="BryanLitz, post: 449138, member: 7848"] As a bullet designer, I can tell you my problem with the .277 caliber is the prevalence of the relatively slow 1:10" twist rate in most factory barrels. That's quite slow for this caliber, and can't stabilize long high BC bullets. The 150 is about the highest BC bullet you can get for the 270, and it's an underachiever compared to the options in .264 or .284 caliber. Of course these are just BC considerations which are just about irrelevant at close range as stated above. With the high velocities attainable with the .270 Win case, inside 400 yards, no deer's gonna know the difference. DRT is DRT. My Pappy shot a .270 for whitetail in PA since my Dad was a kid and I don't remember any stories of deer getting hit and not dying. Granted a long shot where we hunt is 100 yards. -Bryan [/QUOTE]
