Thread: 223 Brno query

Check your twist rate with a cleaning rod. 55gr is bout max for 1:12. You want penetration on bigger animals and the lighter 223 bullets aren't designed to give that. The copper ssts and the like may give the desired penetration but they don't have the oomph to do the business if they miss something vital.
I firmly believe that 1000flbs at the target is the min you should use on reds and above. You do hear of people dropping them with 222 and 223 but you never hear of the ones that got away with no jaw, or a football size hole in the shoulder that only goes in an inch or so.
