Paul, don't know how far down the road of vintage guns you've gone to this point. But in addition to the good advice you've gotten above on the gun you're looking at, I'd add a bit more. If you're looking at older English or European guns, don't assume that just because they have factory 2 3/4" chambers, they're good to go with all or even most current American factory ammo. There's still a pressure issue that must be considered. Proof standards for most of those guns were not the same as the current SAAMI standards in this country.
