I had a chance to get out this afternoon and shoot some of the FFg Pinncacle. Everything went very well, except it did take some additional time to get the FF through the powder measurer. In some ways it worked out good this way, because it slowed me down and helped keep the barrel from heatingup.The Pinnacle powderburns so clean that I was able to shoot and load time after time without cleaning. It was really nice not cleaning between each shotand the accuracy didn't seem to suffer either.
I was shooting my .50calT/C High Plains Sporter w/1-48" twist, the 348gr. Aero Tip Power Belts and a 100gr charge of FF Pinnacle. This rifle has a 24" barrel and I was getting 1450 fps with a 25fps deviation ina 5 shot group. At 50 yds. using a peep sight I was able to shoot 1" groups with this load.
Just for the heck of it I shot some Triple 7, FFg through the chronograph using the same 100gr, powder charge and the same 348gr. PB I recorded 1609 fps with this powder.
When I got home clean up was a snap. I'm very impressed 1st time out with this powder, but I would recommend the FFFg.
I did shoot some Goex Clear Shot today too.This little rifle always liked this powder and that's why I brought it along.I have about a 1/2lb. left. I got 1220fps with this powder. Same bullet and powder charge as above.

MLKeith,
I usually get great groops out of the 348 PB's @ 100yds. After that, the accuracy seems to suffer and is really bad once I get to 200yds. This is using a 150gr charge of Pyrodex Pellets out of my Encore.
