welcome! my encore likes 100 gr pyrodex with 275 gr precision bullets dead centres. I hate the clean up after pyrodex, so I'm experimenting with cleanshot. the purpose of the hornet conversion is to reduce the amount of spark needed to ignite the powder. the theory is that the 209 primer puts too much flame to the powder, causing inconsistent ignition, which causes fliers. in my humble opinion, the most important benefit is that you get NO blowback into your action. with the 209's, you do get fouling in the action. so, when your done shooting, be sure to pay attention to the action and breechface as well. good luck.
