CYCLONE i hunt squirrels with a ruger super-six so lets not touch my shooting skills nor will i touch yours. that's not the point here. lets just say if you could pump up your bb gun so it would produce 2000fps would you use it on coyotes or woodchucks. i don't think so. of the so called dozens of woodchucks you shot dead on the spot with your .17 how many others ran down the hole or laid on the ground kicking for a short time.. i'm guessing quite a few times when you thought you missed were actual hits and the animal made it home before they died. it's just not fair to the animal to under gun it. there is just not enough mass in that bullet to produce the wound channels needed to dispatch most animals quickly. speed is not everything. i think the best thing to shoot with that caliber would be paper or the small animals that were discussed earlier.
