I use a light coat of copper grease.

Never seize

I am with Tim I use never seize
Works really well for me and I change barrel all the time

Moreys Bigfoot grease on barrel and bolt lugs. Stuff takes a long time to dissapear as its really thick and sticky.

For those who are using Anti Seize a word of warning !!

When I was a member of a Race car team we had many sponsors and 1 sponsor which has to remain nameless for legal reasons , supplied our team with many lubricants,greases etc and ANTI SEIZE . I was informed by the manufacturer that some Anti seizes have a very large metal content and are extremely abrasive to the threads and was advised NOT to use it on certain parts of the car or on precision threads or tension bolts.

I change barrels all the time and I would NOT use Anti Seize on my action threads..

Brett I use Permatex anti seize on my threads which is very high in zinc. Not sure if is abrasive to the threads...
What do you use now?

I use 2 products, With no particular preference, Nulon LM 90 extreme pressure grease, or another WD 40 product, white lithium spray on grease. Both work very well.

Steve I use Morey's EP2 grease on my action threads and Bolt lugs. I found it stays in place longer and has over 70 on the Timken pound out meter which means it handles high shock load very well..

This is the stuff. Its bright orange in colour.

Chased up some Morey's bigfoot grease. Great company to deal with. A couple of calls and the rep.from Tas. Bearing and chain in Burnie has left me a cartridge at the nearest town to me.

As a mechanic, when ever we change oil seals usually the seal manufacturer supplies seal assembly grease, it is grey in colour and looks like it might have some Moly in it. I have wondered if it could be used on the bolt lugs. I have dozens of small tubes around unused.
Another mechanic has mentioned that you would have to check the melting point of the grease, as if it is too low you will have liquid slime running through your action!

Interesting comment re anti-seize being abrasive. If that is the case then galling would be much worse using the stuff. I've never seen thread wear in stainless bolts and studs on equipment that is regularly torn down and overhauled. That's using nickel anti-seize. The copper based stuff works ok too.

I guess softer steel grades may suffer though. I think any good extreme pressure grease with a reasonable working temperature range does the job ok.

Been using Magnalube, good temp range and contains PTFE on my bolt lug and spring
