Today I stripped my rifle from it's HS Precision stock and saw a build up of what looked like rust and hard water stains and build up behind the recoil lug spanning the area of where my action meets the aluminum block screw would be placed, upon further inspection I also saw the same buildup of gunk/rust where the safety area underneath the action meets the aluminum block and screw. I lightly sanded, cleaned and oiled both areas along with the aluminum block of the HS stock. Now that all of the gunk and rust are gone is it safe to say that this is where my inaccuracy could have stemmed from?
This could have caused the accuracy problem, but you have not cured the corrosion problem and
it will happen again.
When dissimilar metals are placed together and H2o is added it is almost a certainty that corrosion will follow.
I believe in bedding "All" actions In stocks and the fact that there is an aluminum alloy bedding block
does not change that because they don't fit perfectly anyway, also the corrosion issue is resolved by
the bedding compound separating the two dissimilar materials.
Do a good bedding job and you can eliminate this problem and if it still doesn't shoot well look at the scope, bases and mounts.
