RE: Powerbelt 270grn. Platinum bullet performance
The company recommendation for normal Power Belts before they came out with the platinium was 70 to 90 gr of black or RS as I remember it; I understand you shold be able to load the Platinium a little bit heaver. The principal which operates a power Blet is quite different that a sabot as the upset to the size of the barrel and fill the rifleing so they are actually a conical. Used right they can do an excellant job at 100yds or less I would suggest that even with a platinium 110 gr is more than enough since their balistic coefficiant is about .06 and more powder is more likly to cost you a deer than get you one. If they ever come out with a round nosewith a bit harder lead they might be able to handle mag loads.Lee
