I'm looking at getting into the singleshot rifle game (mostly for $$$$$$$ savings, I really like my bolts and levers).
just picked up a 99% (ding in stock) H&R topper in 12ga, with a 20ga barrel, drilled and tapped, at auction for 85 bucks. don't know if that was a "deal" or not, but then started thinking "could I use this for handgun calibers".
guess what I'm wondering is, is the shotgun receiver the SB1 as I have seen stated on here, and if so, how high pressure a cartridge should I dare to shoot off a shotgun receiver. (I'm thinking .357/38, .44 mag/spl, 30-30?)
don't want to get myself hurt here, just looking for lower cost caliber expansion units
