The 190 gr ABLR from your 300 RUM at 3100 fps will be a long range hammer for sure.

QL released an update on 12 Jan 2014. Mine is ordered, but it may take another week or two before I see it.
Hey Fotis....it seems like you are a proponent of the hornady concentricty checking and correcting tool.
Is that group another demonstration of ammo run past the tool?
(And of course a marksman w/ nerves of steel, a trigger finger as smooth as fine silk, and the eyes of an eagle?) Didn't want to be unfair here...but you DO shoot some phenominal groups!

Thank you!
Kraky. That was not with the gauge. That was a test with the torque wrench on the stock screws set at 35 45 55 inch LBS. This group was at 55 inch lbs. Another variable that many do not take into consideration.

Synthetic or Laminated stock on that 75 ?
Most Sako's are great Shooters
It looks like a keeper.
