223 Rem and a 6BR don't use the same bolt face. A std. 22-250 would serve you well. Keep the barrel cool and it will last 2,200-2,300 rounds of usable life! Go with a 12tw. and 53gr. VMax bullets or an 8 tw. and 75gr. Amax bullets! Depends on how far you want to shoot? Not all that bad if you ask me?
