RE: Maximum Range??
a regular .22 the range is probly 40 yards no more. The 270 is good for 400 plus. I would choose any of these. .22-250(300yrds).222(150yrds) .223(200yrds) .22mag(100yrds) .22hornet(100yards) 12 gauge with #4 buckshot(50 yards)
The yards may not be exact someone might be able to do better but those are my guesses. You can do longer shots with all the guns but those are the most effective yards.s
