My 10/22 is coming along nicely. This started as a standard 10/22 carbine I picked up a month ago. I've swapped out the barrel with a Shaw bull barrel and added a Hogue stock. I've got an extended mag release on the way and a longer charging handle which I wasn't going to get but the scope turrets kind of get in the way. The scope is a Simmons Whitetail classic 4x, where I am the longest shot on anything, let alone a squirrel is probably going to be 60-70 yards tops. I've got a Caldwell bi-pod coming for it too. Today I broke in the barrel, which was with CCI Standard velocity ammo. Per Shaw's instructions, I fired 30 rounds in 5 round strings, cleaning the barrel every five rounds, and then 70 rounds in ten round strings, cleaning every ten rounds. In between strings I also adjusted the scope, but today wasn't as much about accuracy as breaking in the barrel. I will play around with group size later when I shoot it again.
