I would rather hunt woodchucks than anything else! I started in 1964 and still do it when I can. But there us less available land to hunt and the 'chucks are getting scarce due to coyote activity. Here in Central New York state there were effectively no coyotes in 1964, but there are plenty now. One set of fields that I used to hunt always had plenty of chucks, but in the last 10 years I have only seen one. While the farmer and I were talking a few years ago, a coyote sauntered thru the field and didn't even pay any attention to us. There is more posted land now and more houses. Roads that had no houses on them in the 60's now have enough to the point of not being able to get far enough from one to legally shoot.
The previously mentioned fields are now posted due to new ownership. I still have a couple of farms to hunt that have quite a number of 'chucks available. Good landowner relations has always been the key to having available hunting land. Just the other day I was given a lead to a farm than might be huntable. I stopped by and talked with the farmer for a bit and got permission to coyote hunt, I didn't see any, but I saw him when I was leaving and we had another conversation. When I mentioned woodchucks, he was very enthusiastic about giving me permission. He even offered to pay me! I'm not going to take up that offer, but will sure try to develop a good relationship with him this year.
My 'chuck hunting methods have changed over the years due to having less land available and therefore shorter ranges. Also, I really don't want to get the natives all riled up with a superboomer caliber. I used to use a Remington 700 in .22-250, but ran out of places where the range capability was needed. Sinjce then, my "long-range" calibers have been the .223 and .17 Remington. I find myself using my Contender carbines in .17 HRM and .22 Hornet most of the time. With the .17 HRM, the noise is low and the range is adequate for most places I hunt. I just picked up a .204 Ruger Contender carbine at the T/C Classifieds here at GBO, and plan to try it out this year on the longer fields.
