Whenever I acquire a bolt action rifle, whether it's used or brand new. It is "new to me"!!! Consequently, I am curious as to what is beneath the surface to know what I've got. So, I take 'em down and clean everything. Then, using Inletting Ink, (which comes in black and gold), applied to all the barreled action surfaces where it joins with the stock tI can see where it's touching and not touching. I haven't yet found one that couldn't use some attention.
