Just a thought on the p.o.a. shifting when you remove and reattach the stock, if when you first get the rifle and clean it remove the stock as well to make sure there isn't anything left laying in there from assembly, (it only takes a spec of something to change your bedding and it happens).

When putting it back together use a torque wrench and adjust to the specs in the owners manual, if you do this from the start each time you remove the stock you will probably have very little need to readjust the scope as often or as much.

Has anyone weighed their tr before putting on your scope etc. I just wonder how close the true weight is to the stated weight, thanks. blue
