I haven't measured them...but it shoots a 240xtp better than I have the capabilities. I'm getting 2" groups at 50yds using iron's...which I can't complain about considering it's a 4 3/4" barrel. Just while shooting, I figured I would try the cast.
I got cut short on my post earlier: as I was saying....I'll have to check when I get home, but I think the 300 MBWs are .430 but not positive; they may be .431. Wasn't sure if the longer bullet may have had something to do with the tight fit. I'm fairly new to shooting cast so forgive me of my ignorance on the subject. I'll do more in depth work with the cast after hunting season, but right now I'll stick with the jacketed.
