I've seen several references to Gamo barrels being "oversized". Just what does this mean, and how important is it? In a response from Jim Maccarri regarding parts for Gamo's, he said that Gamo's have oversized barrels, and because of that, virtually every shot is a dry fire. We all know what that means with a springer. So what, if anything, can or should be done about it? Is pellet choice the answer? I know that JSB offers Exacts in three different head diameters. But if there's no difference between the three, that's no help. Custom after market barrel? I bought a $200 CFX because of wallet limitations! I know that a Lothar-Walther .177 choked airgun barrel is available for less than $100, but I know nothing about installing one. I do know it's not as simple as changing barrels on a Ruger 10/22! Reality is, by the time I get my CFX back from the tuner, I'll be into it for close to $600. That includes replacing the scope it came with, but doesn't include pellets. Glad my wife doesn't know the total to date

! So, any ideas/suggestions/opinions would be much appreciated. After all, this directly impacts the longevity of my gun. Thanks!
