I understand Tate and crew over at impact like the Lucas red and tacky grease for their actions.

This is my first high end action, im sure im over thinking it but anyone have a diagram where I should grease and what parts need a little oil?

Im from the world of pistols, just want to make sure I start with good habits with this beauty. Thank you in advance!

No picture but the main area is the rear of the bolt lugs. You could place a dab on the cocking piece. Borrowed from MDT.

I put LB 8012 on the back of the bolt lug and the rear cocking area. Additionally, when cleaning the bolt body I will wipe “Free All” penetrating oil on the body and wipe it off. Found that trick out by accident a few months ago.

In the old days, it was well known that XP100 bolts would gall without a slight dab of grease at the back of the locking lugs. Always worked and never an issue UNLESS,

In my mind, if you did not clean them often, they would pick up grit and grind away the action as you worked the bolt. (We shot a whole lots because our loads were light and barrels simply did not Seem to ever wear out)

I still follow this practice but as said, I make it a practice to throughly clean the outside of the bolt body, lugs and action to rid all of the old grease before applying fresh.

This is Mil-Comm high-temp lithium gun grease, it's made for barrel nuts on machine-guns and stuff. Works great. Like was said before... Just a little on the back of the lugs, a little on the threads of the firing pin shroud after you remove it from the bolt body, and a little bit on the cocking piece if you want?

I just got a tube of this. Do you find it to be really runny, then come out with a more viscus consistency? I feel like it needs stirred, but can’t really do that in a squeeze tube.

The Aeroshell 33 I have came in a plastic cup with a lid, like you see in the picture. I use small model paintbrushes to apply the grease. Mine is never runny, but I also keep it inside at room temp year round.🤷🏼

Run them dry. Much less likely to have issues that way. Especially in windy and dusty conditions with shit sticking to the bolt causing rough feeding. Action and lugs are both dlc coated and the same material so galling is not an issue. Zero reason to lube them, in fact you are more likely to cause an issue with grease migrating into the trigger and locking it up.

I shoot 95% of my matches in windy dusty environments. Greasing the bolt lugs and then oiling the bolt body and then wiping off the oil has yet to hurt anything or cause problems. Just don’t use an egregious amount of grease on the lugs, a little goes a long way, or leave the oil on the bolt body.
