I am by no means an expert, having taken up with and immediately enamored with my Encore 50 caliber last year. I started using Blackhorn 209, about 90 grains by volume, pushing a Harvester sabot with Hornady 240 grain 44 caliber xtp with great accuracy and medium recoil. I find the Blackhorn 209 easy to clean up, even more so with a product called "froglube". This year i'm experimenting with the Lee 44 caliber flatnose 310 grain bullet mold. I just cast some using pure lead (soft). I plan to use the same Harvester sabot, they fit perfectly, and try to get an accurate load in the 1400-1600 fps range. I'm thinking this would put the thump on deer at my usual shooting range at under 50 meters.
