Have shot uptwocansof Pinnacle 2F and one can of 3F. Accuracy was the same with both powders: About 1.25" to 1.5" three shot groups at 100 yards with the .430 XTP and 140 grains of 3F. The 3F probably has a little more puissance than 2F. Will take the gun out again tomorrow and work up a load that will put the 250 grain SST to that same point of impact at 100 yards.

I like two loads that shoot to the same point of impact. Did this for my CVA Mag. Hunter and it puts the 300 grain XTP and the 240 grain XTP to the same point ofimpact with 140 grains and 120 grains of Pinnacle 2F, respectively.

My Encore likes a tight fitting sabot. Pinnacle; like JSG, likes to be firmly tamped. i put a fruniture knob on the ramrod and really lean on it.
