Weatherby, just to let you know (you may already know), the barrel fitting is needed for the initial new barrel purchase only, not for every time you change barrels. After that it takes the owner much less than a minute to swap barrels on his gun, very easy and straightforward swap, remove the forearm with a phillips screwdriver, drop the barrel from the receiver and place the new barrel on the frame, replace the forearm with the phillips screwdriver and your good to go. With a survivor forearm it's just loosening a knurled nut that holds the forearm in place, no tools needed. Also many here are now fitting their own used barrels so it's even cheaper. As far as shotguns go, you can buy a new Pardner (H&R shotgun) in any gauge from Wal Mart for $79.00 to $89.00. For sake of discussion lets say that was a 12 gauge, look around and buy a used 16, 20, 28, and 410 barrel for about $30.00 each used and fit them yourself.
For just about $200.00-$210.00 you can have a combination shotgun with a full set of barrels in 12,16,20,28, and .410 bore. Granted, the 28 gauge might be difficult to find used and more difficult to find for the price of $30.00, however if you really wanted it you could order it new from H&R for $39.00 plus the shipping and fitting fee, still a great deal.
I would guess if one were interested in getting a full range of gauges for his receiver he should start by buying the 28 gauge new first since it is the hardest to find used (and they all cost the same new anyway), then look for used barrels in the more more common gauges, 12, 16, 20, and .410. If you really wanted to be versatile you could start with a higher strength SB2 rifle receiver than look for addittional rifle and shotgun barrels....<><.... :grin:
