Anyone done a 80% 10/22 magnum?

[RJLou]

For a long time I have really wanted a 10/22 magnum (but don't wanna cough up $700- $1k for one) and ran across the 80% receiver from select fire. Looks simple enough to do with a drill press.
Has anyone here done one?

Yeah I got one still sitting in the closet haven't gotten it to run right yet. Check rimfirecentral there's several threads on building them.

I did mine with a drill press and it worked but I'd suggest seeing if you can borrow a mill for the barrel hole.

Been there before and forgot about that site. Used the tips and tricks section to do the stoning the hammer and bedding. Just browsing I couldn't find anything, guess I'll have to join so I can use the search option. Thanks for the info guys.

BigNick, did you do the magnum or the lr? What is the issue(s) you're having with it?

[BigNick73]

Magnum. The cases are bulging in the rear and occasionally ripping the rear of the brass off when it shoots. Which in turn blows up my mags if I forget to take them out before shooting.

On rimfire there is a whole 10/22 magnum section all the threads are under there.
