Could have been a special order.
yes it did. i own a heavy barrel 225 Winchester model 70 ,
Do a search for Jarvis. They make a bull barrel for the $597, it runs $198 in either blued or stainless.
Impossible to answer without knowing make and model.
not many....the .17 HMR was only out a short time until Winchester stopper making 94's in all chamberings, not just 17 and 22
Value is based on make, model and condition. We need all 3 factors, you gave us one factor. No answer possible.
No. Also, Marlin does not sell the barrel for the 882 as a component part. The Model 17 barrel can be installed, but again finding the barrel is a problem. The existing barrel can be relined to .17HMR. sales@countrygunsmith.net

You did not specify the make of your Model 300 (there are several), but in general, a 12 g shotgun CAN fire slugs from any standard barrel. You will get better accuracy from a slug barrel, but you could use any barrel OTHER than an "Extra Full", or a shotgun with a variable choke.
The value of ANY firearm will depend on the EXACT make, model and condition. The Ruger auto pistols can range from $100 for a well worn Standard Auto with the 4 inch pencil barrel, to around $600 for an excellent condition heavy barreled 6" Model II Target version.
