Hey guys, this is like my second thread ever on THR, so go easy please.
I tried doing a quick search but could not find any threads.
I recently loaded up some 65gr. GameKings for whitetail. I got one deer with it, left brain all over the field, absolutely no meat lost.
I know head shots aren't encouraged, but it was about a 75yrd. shot, so easy pickings.
However, I used the very advanced form of sighting in my 1/9 twist AR-15 by shooting small (smaller than a baseball) rocks beforehand and all seemed well. However afterwards when we went plinking again I figured taking along a few targets was a good idea. Most of the shots seemed dead on, but one was a perfect keyhole about three inches low and an inch left at 40yrds. or so. No one I ask has any explanation.
I've shot many 69gr. MatchKings before with sub MOA results, and never anything resembling a flier or keyhole. I believe the 65gr. SGK is shorter as well as lighter than the SMK, so I would think that my barrel should be able to handle it.
In summary:
RRA 1/9 twist 16" chrome lined barrel
65gr. Sierra GameKing
26.0 grains of H335
Lake City Brass
CCI primers
Only one shot out of dozens keyholed about two inches to the five o'clock on the target at a distance of 40yrds. with the rest performing about MOA or better.
Any thoughts?
