28-30 may help some, but I've found 22-24 to be sufficient enough from my experience. I'm not going to claim to be an expert though, I just really enjoy shooting. I had concidered doing a 22 inch myself. 24 just has been stuck in my head for whatever reason. I have had countless amounts of people tell me I need a Kreiger level Barrel as well, yet I'm on a budget with this gun, and I'm still going to be purchasing a scope for it, which buying a Kreiger would limit me drastically. I feel the money would be better spent on a great scope.
