Best varmint round?
I'm wondering what the best all around round for shooting varmint (digger squirrel and wood pecker, sometimes coyote in my case).
The cartridge I'm really curious about is the 17HMR. How does it compare to a 22lr?
Also I read that either a 410 shotgun or a 20 gauge with size 6 brass would be a good option.
Honestly Im overwhelmed by all the choices so any help narrowing it down would be appreciated
