cwlongshot did his .35 Rem barrel by hand.....but....ya gotta remember, he's a very careful and meticulous person. If you're a klutz like me, you wouldn't do it. I don't even do mags to maxis myself
I'd take it to a gunsmith or a machine shop. Besides, what's easier, reaming a .35 barrel you can't find or a .357 you can
