I ran into a few issues on my zero looking for input. I shoot all factory ammo, Barnes bullets as I am in CA. All standard Tikka stocks, not bedded, but I have free floated the barrel and shot off a Spartan bi-pod and rear bag at 100 yards.
Now I have been through the ringer in the past 6 years...3 junk savages, 3 leupolds (all failed) and 3 years ago drank the koolaide and now have 3 tikkas, with UM rings and NF NXS scopes. I have done the full degrease and properly torqued everything; real bottom metal, torqued action, ring bases and top caps all with locktight. The 7rm is a 1.25" 20 shot group. The 6.5 is about 1.65" group and the 308 has never shot great at 2-2.25". The 308 went threw 3 rounds of ceretoke (orange peel, wrong color then the right color, what a mess and may have affected the rifle...unsure).
So here are my last 3 groups with the 308 over the last 18 months. What did cahnge from the 2nd and 3rd round is I read about if your bolt handle touches the stock it can be an isue so I grooved out the stock. Also I could have adjusted my zero wrong last time. You can see my notes on my adjustments. I plan to go back in the winter after season (308 is a back up gun) and shot 10 rounds and see where I am at.
Anyway...and thoughts?
