AIRWOLF AND .25 33.95 MKII's

My opinion is at this point? This gun is under powered to shoot these pellets. Out of the barrel It's down to 750 fps. That's a 100 fps plus drop. Shooting a 1 1/8" dinger at 60 yards was disappointing. I thought it would swing that ding! not so much! Have to see what it does on paper.
Think I'll check out some lighter ammo. Anyone have suggestions?
