LOL, I have looked into a tank, but I'm OK with pumping once I get the gun tuned to deliver 20 useable shots instead of only 10. It's not so much hard to pump, just frustrating to shoot only ten shots before having to pump again.And I have tried CPUM's, and they group about the same as the Winchesters for twice the price. 1/2" at 25 yards bone-stock gives me a gun that I feel comfortable using out to 40 yards for small game and pests, and a tune with trigger job and recrown should stretch that to 50 yards, which is realistically all I need.
