I have both in a NEF and find they are both very accurate.
So far I havent' killed anything with the HMR.
But, I shot some prairie dogs with the M2 and was disappointed in the results.
One was a head shot and was a good result with half the head gone.
The other was a center body shot laying across the mound sideways to me. Both
were on the same mound at 60+- yds.
The body shot rolled it over and I figured that's a dead one too. So went to the other end
of the town and started shooting working my way back. There wasn't many out that day for
some reason. Think they recognized my truck and knew what I was up to. Although I've only
shot them up about ten times this summer, they learn fast.
When I got back to the first two, decided I'd go check out the damage this round did to them.
Like I said, the head shot was half gone, very good.
But, the body shot dog was still alive!! This was some half hour or so after it had been shot in
the diaphram area. To me, this is more than unacceptable!
I want to warn anyone to make damned sure you can make head shots, or proper chest, spine shots
or else don't shoot animals of any kind with this cartridge.
I will be careful of my shots from now on and may very well use this barrel for my center fire conversion
to .17x28mm.
