Keeping the accu-trigger in tune?

I have a custom FT/R rife built on a Model 12 Dual port (Right bolt, Left Port, Right eject) action, barrel is a 30" LV Krieger with a shoulder (no barrel nut) Stock is an unknown laminate. My question is actually regarding the accutrigger. I have to readjust the accutrigger relatively frequently (every 3-500 rnds) to keep the pull weight the same. It always works itself lighter, to the point that I cant close the bolt without tripping the sear. Does anyone have any tricks for keeping the target accutrigger in the same tune as you set it at? Right now I just have an index mark on the back of the trigger and on the adjusting spring, so that I can just go line it back up.

A little blue loctite on the part of the spring in the trigger ? That should keep it from working loose.

Contacting Savage may be worth looking into.
Another might be emailing Sharp Shooters Supply to see if they may have an answer for you.

Please keep us posted on what you come up with. I have a Model 12 F Class with the Target Accutrigger, but haven't shot it enough yet to know whether it lightens up on mine.

I use loctite In the adjustment spring hole. It won't setup, but it will get sticky enough to keep the spring from rotating.

Why wont it setup?

It sets up in the absence of oxygen. The loctite tube is actually permeable.

A dab of nail polish.

I wonder if the spring is loosing tension or if its rotating?

It's rotating.
