Fern, you know me. Have I ever steered you in the wrong direction?
After your experience with your 11t 204 Match Pac-Nor rifle, the logical next step (to me) would be a 20VT on that CZ with another P/N barrel....3G 12T. Your 204 is good in the PD or rat patch out to farther than you'll most likely ever shoot a small varmint. Inside of 400 yards, a 20VT will serve you very well and not burn over 25grs of powder doing it. It'll go out to 500 on squirrels or PD's though if ever needed.
Almost no recoil, minimum blast that adds up after a few hours of continual shooting, miserly on powder; 18.5grs gives me 3,700 fps with the 32gr, see all your hits through the scope, and you really don't have to clean as often. I usually go 50 - 75 rounds before I do, and it's only because I want to, as the accuracy still is there. I've even gone 100 rnds downrange when the shooting was too good to stop. Again, no apparent degrading of accuracy. You'll also notice a distinct lack of barrel heating. Heat is a barrel's worst enemy.
Barrel life is very good also. Mine has just ovr 5,200 rounds sent downrange, almost all at hair, and it still shoots in the .2's. It's just about the finest cartridge for PD's and sage rats inside of 400 yards to ever come down the pike. Todd Kindler, the originator of the cartridge bugged me for five years to build one. Once I had mine in hand and had come back from a rat rodeo, I told him about it and my experience. The reply from Todd: "Told you so". 'Nuff said.
Because of my associaton with Nosler, I shoot their BT's and Varmageddon seconds for the value. One does not need expensive match bullets to shoot colony rodents. Here's a comparison of both in a test I did a while back:
Note that both targets were shot with Nosler 'seconds'. Not much else to say in that regard.
With a couple of fellows here on AS, you can get fully formed and ready to load 20VT brass too (The CZ Kid is an excellent source). I just form from Lapua, Nosler or R-P using a Redding body die, then a bushing neck die, neck turn, load and shoot. Like you, I don't mind spending time in my gun room forming or prepping brass.
Oh, and I'll add that the 20VT is also quite the chuck medicine too:
Lots to like about the little 20VT.
