Like a couple others I have, it hasn't been to the range yet, have ammo loaded up for it tho. Booyah did mine before I bought it from him, he did his on a lathe, I don't think I'd do one by hand, too easy to screw it up, you could always salvage it to a bigger .224" round tho, 223 ejector will work. You'll also have to convert the underlug for rimless ejection, that's covered in the FAQs.
