I have seen a few posts on the cast bullet association about guys doing cast bullets in the AR with a 1/7 twist barrel, I was wondering if anyone here has done it, if you have what alloy, bullet mold did you use and how fast did you run them?
I was thinking on using a 225-72 RN, it looks a lot like a 22 cal 311299 bullet. I figure a 72gr bullet would be easier to get to work then a 55gr
I am curious to hear what people have done.
