You can kill every animal on the mountain with a 2" grouping rifle, ha. It will settle down, and so will you. I had the same rifle for years, but had it pillar bedded/floated and a trigger job. Though I shot it a bunch, it was my marine SIL who hunted with it. He shot a mule deer with the 180AB. His friend uses a Tikka and has killed deer and elk for several years. I sold it to do something or other. I found that a case full of TAC and the 160TTSX gave me 1/2" groups of three and averaged 3007fps! Wicked. Good luck to you Pard!
