Custom Action longevity again!

[swd]

Has anyone ever done a hardness test on an action with 100K rds on it, or would this be a moot point?

A non issue.

You might consider that a lot of gas operated and OU skeet guns may be fired 200,000 to 400,000 times by a long time competitor.

remember we are talking about "custom" actions that are made to modern day specs.,,,,not a military mauser or some other antique action ,,,,,if the action was soft it would not have made it to 100,000+ rounds,,,,Roger

Im going to go against the grain here and say it depends. I know my Defiance Deviant has had some bad, abusive days in the middle of PRS matches. Any lubrication attacts dust and debris...but you dont have time to clean. You gotta run the gun. Last year during the PRS Finale in Oklahoma I did a fair amount of bolt and raceway damage as well as light scarring to the lugs for going about 2-3 stages longer than I should have without cleaning. Last weekend I started to foul up about 6-8 stages in to the day.

I expect my action to go about 30,000 rounds, then it will probably need the lug faces cleaned up, hone the action bore and then send it for sandblast, electropolishing, and then DLC. That should help it handle the conditions a little better.

That said, if you keep them clean... they should outlast you.
If you dont... you get what you get. A bad match with Afghanistan like dust will kill an action quick.

Keep it clean, is about the best you can do.
Any sand or dirt is harder than any steel.
Never ever sand blast an action. You embed microscopic fragments of sand in the surface.
Honing the action bore only makes the fit looser.
Electropolishing is primarily a corrosion prevention process or a cosmetic process. Neither helps the function of an action. The first time it is used the EP finish will start being damaged.

If you remove the firing pin assembly does the bolt drop freely in the action ?

The saddest part of aging ..... not only do I not remember HOW ..... I even forget WHY!!!!

Like the old Indian used to say "Me know how, Me want SOME"

Nolser uses NULA actions on their test rifles and I think I read some have a million rounds through them.
