Has anyone tried the new BPI RSS-12 sabots yet? I'm getting into slug reloading. I don't have any casting equipment yet and figure these sabots might be a good place to start. They seem like they would work well with the 350 grain XTP and the 300 FTX 50 caliber bullets from Hornady.
They call for an overshot card for them for the roll crimp loads, which makes sense to me. But how do the manufacturers keep the bullets in their sabot products without the bullets coming out during transport and whatever else?
