22 Mag Winchester lever has been my bunny gun predominantly for the past ten years although at times I use a Ruger Mark II 22 handgun. I bought a Marlin 17HMR bolt this year and will be testing it on the bunnies this upcoming bunny season although it will be quite a bit heavier to lug around then my Winchester or Ruger.
I give a hands up to 22mag although I dont have one. I have a semi auto .22lr that I love to shoot. The only thing i've ever killed with it was a small rabbit at about 15yds and it jumped and jumped around like the ground was a hot plate then expired. I need to do more small game killing with it because its a blast to shoot.
Jim Zumbo, Craig Boddington, Ron Spomer and Wayne Van Zwoll are all solid contributers to the modern hunting literature. Through their gifts (both hunting and writing) they make us better hunters. Whether it is letting us learn from their mistakes or by teaching us new techniques,they help us harvest more game. But I suggest looking to the oldies, the fathers of the outdoor writing craft, to learn tricks that you might have not used.
I chose to shoot the 270 winchester because I grew up...
