[lawdog]

Got to the range late today. I am trying to work up a new load for the smokepole. I shoot a T/C Encore. I shot a Barnes 245 grain spit fire pushed by 90 grains of 777 fffg. The reult was about a 3.5 inch group from 100 yards. Thats with the barrell swabbed in betwwen each shot. I was a little disappointed. I am having trouble associating the difference betwwen 777 loose fffg and 777 pellets. If I am using 90 grains of loose 777 fffg and not achieving tight groups, would you suggest going up or down in volume? Thanks for any help or advice.

Both. Shoot 3 at 100g then drop to 80 and see which shoots better. If that doesn't help you need to change your load or maybe just a sabot. I cant help with that particular gun or load.
