WARNING: If you do not lube the rear of your bolt locking lugs you will increase wear and your headspace faster and take a chance of galling your lugs. This is even "MORE" important with neck sized cases and bolts that close tightly on your form fitting cases.

I collect the Enfield rifle and had a conversation with the senior Armourer in the U.K. Captain Peter Laidler on the Enfield rifle. Now here is the funny part of this because we have Savage rifles with a barrel nut.

One of the reasons military rifles have "LONG" headspace is to reduce wear and reduce the bolt thrust applied to the bolt and receiver. On any rifle after firing the case springs back to a smaller size than the chamber and "takes the load off the locking lugs". On a tightly headspace civilian rifle there is much less "wiggle" room and your lugs "MUST" be lubricated.

Bottom line, grease your lugs we all have tighter headspace than a military Enfield rifle and our lugs have more contact time and force applied to them.

Bolt Maintenance Methods & Materials

1. The Rear Surface of the Locking Lugs
There are two lugs on most bolts, three or four lugs on some actions. Wipe these clean with a paper towel before re-applying the lube. Dab a little of the grease on the tip of the small screwdriver and spread it on the lugs. This should be a thin, even coat. Just thick enough to cover the metal but not globbed on. This picture shows the lugs wiped clean before lubing. A locking lug recess cleaning tool such as Sinclair Int’l offers is useful to ensure that any grit and bits of brass that collect in the receiver’s lug recesses get cleaned out.
