last christmas I bought an HM2 for squirrel hunting, I love to squirrel hunt and I like to eat them, don't know where stiff neck got his info but its inaccurate,
The HM2 does a good job on squirrels, not bad on small groundhogs, but after your game exceeds around 8 pounds it just doesn't have enough bullet weigh to get the job done unless you headshoot them. I did last year shoot a groundhog (a big sow) at 142 yds, she ran a ways, almost got back to the hole, but I'm convinced that if she would have been 50 yds, she would have gotten away, the range slowed the bullet down enough that it couldn't expand like it normaly does.
Now, I will say this I've squirrel hunted for the last 15 years with a tricked out 10/22 and killed hundreds of squirrels with it, headshooting when possible. Of all those 1, was shot in the head, was totaly incopassitated, but wasn't dead. It was a melanistic (black) grey squirrel so instead of clubbing it, which would mess it up for mounting purposes, I just let it expire, took a couple hours, when you walked by it would kick and twitch.
The first thing I noticed was how well my LH savage mark 2 in HM2 shot, absolutely incredible. I put a weaver 4x16 1/4 moa dot on it and am very well pleased with how it shoots and the performance on squirrels is stellar.
The only thing I see is that out of about 20 squirrels taken with it, all headshot I had 4 that were like the black one described above. not alive but not really dead either, one would set up and seemed to be watching me skin the others, kick him over and he sat back up, couldn't go anywhere, don't think it suffered any, I could see brain matter in the bullets path. thats my only complaint about this great lil rifle, I don't have an HMR, don't have a use for it, but there will allways be a HM2 in my safe for hunting meat squirrels, they're not any more destructive than a 22LR on squirrels, and an out of the box 17 will shoot as well as most custom built 22's. If you like hunting and eating squirrel you can't go wrong with a HM2
