Mauser action question

[oldhoward]

HI,
I installed a new trigger in a Mauser Mark X Interarms action. The rifle stock is an older fiberglass benchrest stock. Problem is when I tighten the rear screw the bolt will not cock . It is not hitting anything that I can see. I only tighten the rear screw with two fingers and it may cock and function ok. Tightening the rear screw any tighter and it will not cock. Question is I am I bending the action? The front of the action has been bedded and the rear screw area, very small area, has not been bedded. There is no metal tube around the rear screw. Any suggestions? Thanks, Howard

The rear tang & screw hole should be bedded. I use J-B weld to form the pillar & drill it out with about a 20 thousands clearance or a .270 drill. Be aware that there are a bunch of trigger variations & even if the box said that it was for a Mark X doesn't mean that it's the correct one. I've had it happen.
I would put some lay out dye on the trigger sides, front, back & reinstall it in the stock & look for any contact points. Some of the aftermarket triggers require a little more clearance in some areas. My GUESS is that when you tighten the screw , you are jamming something on the trigger into the stock..

Hi, I did put dye on the trigger and found minor contact. I have removed the contact and the problem still is there. I will contact the trigger manufacturer to see if the part is correct.

You are bending the action because the tang is not being supported properly. See the reply before this one. If the rifle is glass bedded it will need to be tweaked a bit. If it were mine I would rough up the bedding that is there and re-bed including the tang area but use bedding screws and hold the action with surgical tubing or stretched electrical tape instead of tightening with the action screws or you will have the same problem all over.

i have run into this problem before & it's most often the tip of the trigger touching the trigger guard. this will prevent the sear from catching the cocking piece thus will not engage the bolt at all take care------ Craig

Some mauser triggers require the trigger guard to be notched out on the inside of the trigger guard. If you installed a trigger with a safety, it will most likely need that notch. The notch widens the area above the slot where the trigger pokes through, when finished everything that is showing should still look stock and nothing showing should have been touched.

A guess a picture would describe this best.

Measured some rear action screw pillers, they are at 1.500". I will make my own to length when I build a blind bottom stock.
