I'm setting up a contender with threaded 22lr and 30-30 barrels.
I sold an AR upper and some other "stuff" to do it.
I want my son to be able to practice with his hunting rifle, and I have tens of thousands of rounds of 22lr. I'm not running out anytime this decade using a single shot.
I'll probably sell another AR or two if things get really stupid and buy some more components and powder.
