Well I have used PRB in 45,50,54,58 caliber I started out using hollow point lead in a TC sabot that was split and had a greased wad, went to 250 grain XTP Then power pelts, then to Shock Wave 250 grain then to Deep Curl[Gold Dot] 250 grain then to Gold Dot 300grain then back to 250 grain Deep Curl then to Lehigh 200 grain, then the 200 grain 40 caliber shock Wave, then to Bonded Shock Wave.
The best PRB for me is the 54 caliber. I was not happy with the pure lead hollow point, I had a very bad experience with Power Belts, the XTP was marginal they break up to easy with the loads I use.
The Bonded Shock Wave the 200grain 40 calibers and the 250 grain Deep Curl were excellent stoppers and are my go to bullets.
