Everything that would let me get within range. I started with a crossman 760 like many of you and took many critters with it, from sparrows to rabbits. When I was 11 dad started letting me take out his old Western Field 22 and I was ruined. I got just enough allowance each week to buy a brick of remington thunderbolts and I was being real careful with the last box by the 4th or 5th day. That went on through my sophmore year of high school when other interests slowed my 22 shooting down. I took pretty much everything KS had to offer except with it except deer, including coyotes and bobcat. The long barrel and fine sights that were meant to be used made hits pretty regular. I eventually wore the gun out, but had my gunsmith fix it up for Dad as a fathers day gift a couple years back to look brand new. Also had his old 243 re-done too so now they are better than when I first started using them.
