Does any have an opinion why some barrels have a counter bore? thanks, joe
You could counterboreI've read somewhere that it can be a form of tuning...I've seen a couple of sporters with counter bore that shot well,
If you mean "back bored" as opposed to a slightly radical crowning technique, it can do a lot of things, including freeing the bullet from the barrel more quickly before the barrel deviates away from that perfect aim you had when you first thought to push the trigger. My favorite .22 has an 11" backbore to it, but it wasn't actually made by backboring per se. There are easier, better ways to do it.

I'm hoping a light bulb may go off for me. thanks, joeThere are easier, better ways to do it.
It is more work trying to tune with back boreing..... I think it was the Winchester 52E's that were back bored a 1/4 of an inch or so. Was this "countersink/back boreing" a form of tuneing? joe
