Where can a guy get a decent one to build up? Wasn't some of them converted to 35-303 for rifles in Canada and the NW? POWDR
Good luck with that. In my gun-smithing years I had maybe 2 dozen come into the shop before I started refusing to work on them.
The first thing to check is headspace. Only one of those rifles had proper head-space. This is adjusted by changing the bolt-heads, #1 to #5 IIRC. And it's damned hard to come by some of those. Took me 5 years on one, before I'd let it out of my shop. Fugger had a # 1, needed a #5....
It's a functional rifle and durable, and not something I would own because it is otherwise a cheap piece of crap (ask all the Germans it killed.... but I digress.....
), but if you go for it- make sure it has proper head spacing BEFORE purchase or it will be the major PITA of your gun-owning career.
