I have a stack-'em-in-one-hole Rem 788 in 222 Remington I bought back in days of old. I've often thought about shooting cast in it, but the only 22 caliber mold designs I was familiar with were iron molds. I don't like iron molds. Just recently I got an aluminum NOE 7mm Hunter mold, and although I haven't used it yet it is top quality. So my question is: which Noe 225 mold will likely work best in my 1-14 twist 222 Rem rifle?
