there are many posts on this if you do a search. i have the bolt kit that dolomite was giving away and while it helped it doesnt work the way ss job does.

my advice for a start is while you are watching tv work that bolt at least 500 times 1k would be better that alone will help a lot. i have 2 target actions the one i bought used and had been fired a bunch is very smooth while the new one is rough.
