Over at the Savageshooters forum, we swap barrels about like the Handi, but the funny thing is, a used barrel ALWAYS goes for anywhere from half to two thirds of new price. Maybe a bit more if it's a custom barrel.
There are some factory barrels that are no longer made by the factory, like 220 Swift, that are drawing more, but they are rare. The thing is they ALWAYS fit.
Why are the Handi barrel prices new or higher, a lot of times? I know most can just be swapped without fitting, but it's still a guess, and there's the shipping/factory fitting charge, but still?
