Best rate of twist for cast .300 black out?
Well, I'll start off by apologizing if this is the wrong forum, but after reading on rpm limits, gas checks, and powder coating I figure I could use all the help I can get.I just bought a tikka t3x in .223 and I'm wanting to swap the barrel. I've been reloading for years and would like to get into casting. Low pressure subsonics sound like a fun round to tinker around with different alloys, molds etc. For a 16 inch barrel what twist rate would you guys recommend for a 200-250 cast, possibly powdercoated bullet?
