[QUOTE="Bart B, post: 1157805, member: 5302"] I wouldn't wast barrel life breaking it in; that's a waste of time in my opinion. A given ammo lot of one may well shoot more accurate than the other. Shoot 20 shots into a single group with each, then pick the one that's most accurate. Any less and the credibility of the group representing accuracy to a 90% level starts dropping. 5-shot groups are about 30% credible. Shoot them at 2 minute intervals so barrel heat does't make it bend; very common with commercial rifles. If it does walk shot impact as it heats up, that can usually be fixed by turning the receiver face as it's held in a mandrel in a lathe square with the barrel tenon thread axis then shimming it to clock in for headspace. Any 'smith worth his business card could do that very easy. [/QUOTE]
