[QUOTE="rdsii64, post: 367504, member: 13978"] I know this is a way old thread but I just found it. I currently also have a 12 twist .223. I have shot this rifle accuratly in a mid range F class match.(600 yards) I use a 50 grain Vmax bullet and 26 grains of N133. That combination is accurate enough to hold the ten ring at 600 yards If i can stay on top of the wind. At 350 yards that load will flat hammer anything that is appropriate to hunt with a .223 Now as far as the BC. On paper the heaviest you and I are going to be able to shoot out of a 12 twist barrel is about 60 grains. In the real world I would not bet the farm on anything heavier than a 55 grain bullet. When it comes to loading for a .223 with a 12 twist barrel we have to play to the rifles strong suite. That is driving LIGHT bullets fast enough to overcome the low BC. As noted above I can drive a 50 grain bullet fast enough to be accurate at 600 yards. My load books at 3500 FPS. You can push a 40 grain bullet into the 3700 fps zone with no over preasure issues if you pick the right powder. In fact Fiochie states their factory 40 grain vmax round is running 3650 at the muzzle of a 12 twist 24 inch barrel. A 12 twist .223 will "git 'er done" if you play to the weapons stong suit [/QUOTE]
