I have a Merimack Ballard in 44 rimfire. I would like to find a healed bullet mould to use with it. The base of the 44 rf fits inside a 41mag case and the nose of the bullet is the same size as the outside diameter of the 41 mag case.

I've used these cases from Dixie...worth a call to see if they are still in stock. Won't take a heeled bullet, but are the easy way to get a big bore rim fire shooting again.

I've copied their design for some of the oddball RF cases not listed...works.

Will have to research the specialty mold shops...are some taht will build a mold to your dimentions. BUt are still stuck with how to get a rim fire cases. IF thinking about modification to teh gun to shoot centerfire, may want to re-think cutting on a collectors grade gun. The Dixie cases can avoid that.
