thanks, pulled stock off, there is some light rust, it was showing a date code of march 1987, but there were two small washers under the back screw on the back trigger card screw, they sat between trigger guard and the wood stock, never seen that before, also thought I heard something else fall, but could just be the mess I have on the bench.
So will have to see if these washers are even needed.
looks like rifle might have been fired a couple time and then not used, barrel very clean, but still have to run my borescope through it.
On leupolds site some bases were for nothing above a mag, so will make sure to pick the ones for the big magnum, fairly heavy rifle, will have to put it on a scale.
Someone probably put those washers in for shims so the bottom metal latches or lines up. Probably needs to be glass bedded, but you will find that out when you put it back together.
