.17 Mach 2 not the .17 HMR.

Has anyone tried the Mach 2 on groundhogs yet? Whats the max range it will take a groundhog?

I haven't had a chance to test mine on groundhogs yet because turkey season dont close untill may 15th and the regs. here state that you cant varmint hunt with rimfire or centerfire firearms when turkey season is open. Ive shot everything from squirrels to fox'es with mine but couldnt find the fox, I know I hit it but couldnt find any blood, only a few hairs.
