Stan, did you look at changing the column position to see if your reloader can go from 2 1/2 to 3"? Being able to use a progressive loader would increase you loading speed by about five times as fast. And on the sizemaster loaders all it require is moving the column bolt from bottom hole to top hole. The progressive loaders have two hole options as well. The only thing I'm not sure about is the hold down pin which may need moving as well or may not. Another option is to call MEC and ask them. They are very friendly to deal with. I altered several 650 from 2 3/4 to 2 1/2" which was a lot less easy than going up I think.
