Alot of guys on here use different size 45 cases.Couldn't you just get it chambered in a 458 Win. or Lott case.In most cases the brass is a lot cheaper.You could still use BP loads in these longer cases.I would love to have one of these chambered in a Handi.I woundn't want to use African loads,but for deer,hogs and bear it wound be fun.What cal. of Handi could you build it off of if any.Dave.
