G'afternoon Gents,
  I have a H&R .410 shotgun that was built in 1985 (by the serial code).  Since I have utterly no use for a .410 gauge, can I still use this older receiver for a barrel swap?  I'm thinking 44 mag.  I'd assume it's considered an SB1 frame, so anything of higher pressure is out of the question...  I read about folks swapping barrels out here all the time, but haven't run across anyone using a receiver this old.  I hope I can, because this poor thing has been collecting dust for a couple of decades...
Thanks in advance,
