Anybody else have this experience with the 17 HM2?

Riposte,
experience has shown me that once the weight of the game exceeds 7-8 pounds, you don't have any dramatic DRT kills with the HM2, just not enough bullet weight to get the job done, half grown groundhogs die really fast where adults will almost always get back to they're holes.
Do you have the heavy bolt handle on your 10/22 conversion? If not you are battering your bolt as you shoot it.
