What's a "wood chuck"? You mean "ground hogs" as some call them "Sod Poodles" and "whistle pigs" they are Rifleman's game of choice for long range hunting as seasons if any are liberal with no limits. I do miss my little buddies, not enough here on the shore to hunt as our ground hogs thrive central and mountain regions of Mid Atlantic. I had a nice array of varmint and predator control rifles; .243, .223, 22-250 and two .204 Ruger calibers. My favorite was .204 Ruger, applaud Hornady for its development, .222 magnum case neck down to .20 caliber. I pushed .40 V Max in front of 10X only @ 3600, below max and still was much flatter shooting than other popular varmint calibers. My .204's were .25 -.35 printers so MOA extended beyond normal ranges. The longest head shot was 469 yards with the .204 Ruger using a Leica range finder. The best addition to ranging Sod Poodles hunting far done. The most enjoyable of the .204, low recoil and wasn't any louder than a .22 mag but even @ 100 yards could see your hits so didn't have to check the holes for your kills. Some guys stuffed the ground hog down the holes, others used them for fox & coyote bait while I let them lay for the Turkey Buzzards so the farmer knew I was solving his gopher problem.
Remington was late to the .204 Ruger party, while they produce some 700 .204's not that many and just a short run. Seems the .204 Ruger has faded away from offerings, if you shoot PD's or Gophers couldn't choose a better caliber from my experience laying prone on many soy bean fields.
