Welcome aboard, Jack!! Yes, it is, it's one of the first symptoms of becoming addicted to these firearms, once you get started, there's no turning back!! After a few more barrels, you may be interested in rechambering and reboring one or 3 for custom calibers, just depends on how weak you are, I'm about as weak as they come with 24 rifle barrels and 20 frames, 3 custom calibers, sick, sick, sick, I know!!!
