Tuna....That's one BIG chuck! Nice rifle.
Having started this thread, and gotten lots of excellent advice, I thought I'd pass along my decision.
I guess I can't really get 1 rifle and expect it to be both a long range PD killer AND an eastern coyote hunter. I've been around long enough to know there is no such thing as "1 gun does it all". If I'm going to get into PD hunting as an east coaster, guns will be the least part of the investment. Travel, lodging and meals will far exceed the cost of the gun for just 1 trip. Besides, if I get into a good dog town I'll need multiple guns to let the barrells cool. Then there is the cost of ammunition. In a good town, even using cheapo .223 ammo, 3 days ammo costs could easily equal the cost of a gun.
So there really is no way to "inexpensively" test these waters. Its either get halfway serious or don't bother at all. And that "gopher safari" a few years ago in Bozeman made "don't bother at all" NOT an option.
So here's what I have tentatively decided on as a starting varmint/predator arsenal. .22 WMR (already have that). Savage model 10 Predator in .223 (eastern yotes and chucks) and backup PD gun. And a Savage 12 BVSS .223 (pretty much a dedicated PD gun.
That said, has anyone got any pressing arguments against the 2 choices of rifles/calibres? If not, its time I called my local FFL.
