It is basically is a sabot without petals... No MMP does not make a 45 sub base I wish they did. Sales of 45 sabots is so far down it would take a huge investment for them to build them. Del indicated the other day that 45 sabots represent 1% of the sabots sold by MMP.

You probably already have imagined this but I am thinking about cutting the petals off some 45 sabots and giving them a try, when I get back to the 45 tests later. In my 45's the .452x250 Bloodline with its factory knurling is a near perfect fit....
