Curious if anyone is plying with the 450 Bushmaster. I just picked up a cheep Mossberg for this years gun season in Pa. This thing is fun and a dream to carry all day. However, it has a slow twist 1-24 so reloading will be limited. Factory 250's will put three shots into one hole at 50 but I don't think it will stabilize bullets like the Barns 275. If anyone out there has experience with this round please chime in.
