I've been using Sport Pistol for the last 5 years. 3.4 grains and a 105 grain bullet from my 4.625" pistols averages 612 fps. From the rifle, 3.1 grains and a 130 grain bullet averages 745 fps. I've not seen Sport Pistol on the shelves for a while now so once my supply is exhausted, I'll use Clean Shot and/or Perfect Pattern.
