Nice. just started PC bullets' this year. Ive been very happy with results. Cleaning the barrel has not been an issue at all. Been coating .44 Keith over 18 gr of 2400 with great results. And 358156 GC and pushing them out of a .35 Remington T/C over 20.0 SR4759 around 1800 fps with exceptional accuracy. I PC then size through a Lee sizer. I've dug up some of the bullets and their still PC'd! Gone as far as casting them pretty much dead soft like Black Powder slugs and they mushroom beautifully and their still PC'd!
