Hi, a little feedback.
Recently I bedded the action in epoxy and also fixed the plate/sheet where the 2 front stock bolts are screwed in with epoxy to the action. Shooting cycle feels even better now but the main problem was not solved.
Between the last 2 trainings POI dropped the well known 20 clicks.
Now the last idea I have is to replace the trigger guard with a machined brass trigger guard from Rowan.
