7Green, to give you a little encouragement I just finished power tuning a new M3 .35 cal. for a friend that asked me to build him a banger. I set it up to shoot the FX 81gr. pellets at an average velocity of 925 ft/s for about 154 ft. lbs. muzzle energy, and an avg. V of 927 ft/s with the 79gr. NSA hollow points for about 150 fpe, and an avg. of 842 ft/s with the NSA 93gr hollow points for about 146 fpe.All the best, Chuck
