I’ve killed over 100 groundhogs with the 20 grain XTPs, not by choice (I prefer the good ol’ .22 Mag for rimfire chuck shooting) but because the frangibility of the little HMR bullet and (to me) a slightly quieter report than the WMR was preferable in the close-in areas I was forced to use it on. Will have to admit the killing ability of the little round on our big Eastern ‘chucks surprised this usual centerfire groundhog hunter; I killed ‘em DRT regularly out to 130 yards, and one yearling at 200+ (freak shot.) Shot placement and a long-enough barrel are the keys.
