This week has been good for groundhogs. So far I have managed to shoot four of the buggers. I'm very impressed with the 17HMR.I bought my dad a Mosseberg 817 for christmas and decided to try it out this week.The first two I shot with Federal Premium V-SHOK 17 Grain Hornady V-Max Polymer Tip. The polymer tips made the cleanest kills. The two in the pictures were shot with CCI TNT Explosive Jacketed Hollow Points. These two were taken from around 120yrds. I might have to look into one of these.
