Where could one find a new good pump .22 mag rifle?
Usually they are found in gun stores...!
I'm sorry I couldn't resist that.
The only good pump rifle in 22 Magnum, in my opinion, is the Winchester Model 61 chambered in .22 Magnum Rim Fire.
There have been other attempts to build pump style rifles in .22 Magnum, but, again in my opinion, they have all been less than adequate for the cartridge.
If you are really looking for a .22 magnum rifle, in the pump configuration, you will find the Winchester Model 61 in .22 magnum is priced very high. I have seen them priced from $1300.00 to $2000.00 and that is just too much, even though the rifle is an exquisit creation from Winchester.
The Winchester 9422M is still available at fairly decent prices if you want a good .22 Magnum rifle, although is is a lever gun.
I have a Winchester model 61 in .22 Magnum and one in .22 Long Rifle and I wouldn't sell either, for any price.
