We do a bit of coyote/fox hunting, and I have shot both the CZ varmint in .204 and the Savage 12 Varminter 22-250. I prefer the accutrigger over the CZ trigger hands down.
As far as accuracy goes I haven't shot a more accurate gun than my Savage 22-250. As fas as caliber the 22-250 is a time proven cartridge.
I have taken a fox at 480 yds with the 22-250.
As far as deer hunting goes, I have a Rem 700 in 243. A Weatherby Mark in 7MM. A Browning A-Bolt in 270. And a new Browning X-Bolt in 325 WSM.
-The 243 is great for mid range well placed shots. A great caliber for deer.
-The 7MM is what I have killed the majority of my deer with. 100+ whitetails in Georgia. My longest kill with the Weatherby is around 300 yards.
-I love the 270 but I just needed more punch down range.
-So I got the 325 WSM even with all the hype vs. criticism that the Short Mags have gotten. All in all I love it. Stacking holes at 100 yards. Coupled with the Nikon Monarch X (BDC) its very deadly up to 500 yards. Of course I dont "NEED" that much lead, but it serves its purpose. Planning a moose trip next year as well, so I will definately take the 325. It kicks less than my 7MM, shoots up to a 220 grain bullet, and the balance of the gun is unmatched.
Our leases are made up of recently cut timber, so a 400+ yard shot is very normal.
If you are shooting <200 yards then yes a 30-30, 243, 30-06 are all great calibers.
The only downside of the 325 is that the ammo is expensive and a little harder to find.
