I have a few in 50 cal. I know another that likes them, somewhat. They will give deer accuracy, and might give an edge on an elk if a 50 is desired for that use. I think they now call them the Pennsylvania Hunters or something. I still hold. that if one uses a roundball designed gun and more power is needed, go to a larger bore. If one compares the muzzleloading conicals to the BPC conicals, one sees they still are very inefficient. A 300 grain bullet in a 45-70 still loses velocity pretty fast, whcih is why the military used the 405-500 grain bullets. My Hornady "ballets" are destined for the melting pot.
