you mean black gold, have you checked recently the prices of bh 209?..Ive been using 777 pellets, I started with powder in the mid 90s and changed to pellets for convenience, but I have 777 powder and will experiment with loads..in my knight muzzle loader im getting 2-3 inch groups at 100 yards with 2 50 grain pellets and a 240grain xtp sabot... I want to tighten that up and be able to reach out to 200 yards...I have been using federal primers and have on order the 777 primers to see if the crud ring becomes less, its not a major issue with me as you dont usually get a 2nd shot if you miss and the deer is gone..
