Dave have you shot Bull Shops from your BD-XR? If so which bore size? I am thinking you have said the barrel on your BD is much the same barrel as my Omega... Does he BD have a QLA?
Does your barrel float or is solid in the stock?
He can use sabots but the projectile needs to be all lead... I have never shot or even seen the SSB, but I am guessing that is a sabot/lead bullet?
If I remember correctly hecan shoot powerbelts - all lead version. Does Harvester produce and all lead variety of the powerbelt? Obvious I have no interest on PB's so I have never looked this info up.
