The shotgun I hit better with than any other I've used was a J P Clabroug 12ga 28" Damascus SLNE ¼/¼ chokes. Use was birds & rabbits. For the same purposes the gun with which I did the "WORST" of all was a 20ga 870 fitted with a Poly Choke having length including ventilated sleeve of 27". For squirrels I was mostly a .22 rimfire man but amazingly the rifle with which I piled up the vast majority of the little tree rats over the years was an old Mossberg model 42-MC bolt action with a 7-shot clip. I allowed a co-worker too much on it in a trade for something I had he wanted, & since I couldn't get my money back I just shot it out of it. My experience here was I could use standard velocity LR's (mostly "Canuck" by CIL) & sit myself by a big shagbark hickory or sprawling white oak the squirrels were working, pop one in the head & let him lay where he fell. By the time he would hit the ground the others were already back to cutting. The "Crack" of a Hi-Vel LR would generally clear the tree with the first shot. While that little Mossberg would not likely have won many, if any, shooting matches it would hold "Minute-of-Squirrel head" any time of the day, any day of the week.
