Who\'s tricked out a 10/22, LR with 60gr aguila Sniper sub-sonic Brownells sells a barrel with a 9 twist specifically for this Aguila 60gr load. Anyone try this barrel? Anyone shot these bullets in a 16 twist? How did they work? I'm Looking to build a 300 yard plinker. Anyone played with the 17 Aguila round? Do you like it?
