I have shot PA conicals in my 1 in 66 and 1 in 48 twist rifles and am happy with their performance in both twists. It in my guns I have found the Pyrodex P gives me the best groups. I use 80 to 95 grains of powder depending on the gun. I haven't hunted with them yet but know a couple of guys that have who both say that they were as good a deer killer as anything else they have used.
