I know it is a popular caliber in southern NJ for groundhogs. I have been thinking about it myself but I am more seriously considering a 243 to buck the spring winds. There are farms where I have to deliver and long shots and wind are more of an issue than I first perceived. But I would think if I am at in long enough a 204 will also be in my tool bag as less bang has its place. So many different farms and shots. Funny but I spend more time this spring scouting with binoculars and a note book than actual shooting. Love the 223 as it's a good start.
As I look for my next rifle the one thing I am always taking into account is twist rate and bullet weights. Make sure you keep this in mind as well.
I shoot a re-barreled Rem 700 in 204 with 39 gr Sierras ahead of BLC-2. The original bbl. didn't suit me. If buying another one on a budget I would go with a Savage with an accu-trigger. Tikkas, I'm sure are good but I've never shot one.
