I realize you have different bullets, however, for varmints, especially ground hogs, I love a 40g Nosler Ballistic Tip bullet in my CZ .223. The 40g bullet is quite flat shooting, PBR is +/- 1" from line of sight between about 18 yards and 224 yards, and the terminal performance is devastating on any ground hog I've shot. You can kill a lot of ground hogs in that range.
Anyway, I load the 40g NBT seated 0.020" off the lands in FL sized Winchester Brass Filled with 28.0g of AA2460 lit by a CCI400 primer. I zero it at 200 yards. It's about an inch high at 100.
I've seen this load shoot holes touching @ 100 yards in CZ's, Remington Sporters, and a Savage Sporter, so it will probably shoot in yours with a minimum of tweaking.
