So I will give a quick update. I didn't have much time at the range today so I couldn't go through my troubleshooting process like I wanted but did shoot some groups trying a couple different things.
I have never had a rifle so sensitive to how it is held, but I have also not had a rifle as light as this before either. It seemed the more I held the rifle back into my shoulder the tighter it shot, unfortunately I didn't have a shooting coat so the more it was pressed against my shoulder the more inaccurate I was at holding the sight picture. The rifle does not like being rested in the rear "V" type holder of a shooting sled, it seemed if I made any adjustment left to right or up and down that moved the pressure point on the butt end of the stock it would show up in the group.
The rifle also seem to tighten up some when rounds hand fed to chamber but I saw no evidence of damage to round when loaded from magazine.
After I adjusted my shooting style my results were that I shot 2 three round groups that were ~ .65" group with Federal Fusion 150gr and one just under an inch Hornady SST 150gr. and another group should have been a ragged hole but I flinched on shot 3 and put shot 4 back in the same hole with the first two shots.
So my thinking is that I will get a B&C http://www.stockysstocks.com/servlet...n-Tikka/Detail
stock will aluminum bedding and call it good. Hopefully it will be less sensitive, if not it still can't hurt.
