My friend showed me his H&R 32 and was wondering what it was chambered for. he shot some 32 long colt through it and it realy expanded the brass so I did a web seach and found 32 long colt is only .299" and a S&W long is .314. I'm preatry shure that it is 32 S&W long . The 32 H&R mag may be to much power for it. Does any one have anything they could add about the year ,it is nickle plated but not a break action. Thanks F.K.
