I have a 1:12 twist Remington 788 223 Rem in a beautiful custom stock that's quite accurate with 62gr bullets and lighter. Just got some 55gr Gamekings that's begging for a range session. Otherwise this is a varmint/coyote gun. I'm not interested in using it on edible game such as deer or hogs. Other chamberings are better for that role. For my purposes I'm happy with 1:12 twist
