I have a Springfield '03 rifle which is very accurate and makes a lot of fun to shoot.
But the front receiver screw is getting loose after several shots and the point of impact is moving. When I use pet loads this process is only retarded.
I have even cut a new screw on a CNC-lathe with extra tight threads but that hasn't changed anything.
Some years ago I read in this forum that the reason could be a hollow bedding but the receiver has full cantact to the stock.
I try to avoid little screws for securing the large one.
Has anyone heard of a successful solution or the reason for that phenomenon?

Why not try a small amount of the appropriate Loctite formula?

One small drop of blue Loc-tite should do it.

A drop of blue loctite is a definite help. I will also recommend the lost art of seating 03's into the stock before fully tightening the screws.

Draw the screws up nearly tight and then slam the butt on the ground which seats the action back against the lug. Tighten the front screw first followed by the rear. This used to be standard practice with 03's (from WWII vets).

Thank you for your help!

I will start with airguns seating procedure.
If that doesn't cure my little problem I will use Loctite.

You may also try torquing the screw a tad more than you usually do.

I'm no expert but do you think that, either the screw is too long / the screw head is too long and this won't let the threads torque up. Essentially even with a lot of torque only the screw tip / the bottom of the bolt head tightens up and a few jolts later the screw comes loose. FWIW --- John303.

take the rear screw out

screw in the front screw

check for play

any play, the screw is too long

jeffeo550 is on the right track.also, make sure there's just a little air gap betwween the top of the magazine box and the bottom of the action when the guard screws are snugged up...just so they don't actually touch

Hadn't thought of that Duane.. certainly could be a no gap situatio
