Barrel corrosion (product test)

[GMC403]

I had an old Savage 308 barrel that I was going to toss, so I decided to test some products on it instead.

This is obviously not a scientific test, more to satisfy my curiosity and I figured I'd post the results.

The products tested are as shown. The barrel was cut into short sections and stripped of any oil or residue with brake cleaner. All products were applied as per the instructions.



The test solution was 1 part ocean water mixed with 2 parts tap water. Again not scientific, but with skin/sweat salts and the weather here on the coast, I feel it's a valid test solution.



At 10:00am All pieces were coated.... dried....then coated again with the product being applied. Then I mist sprayed all the pieces and left them in the garage.
(I added the stainless piece at the last minute and it missed the picture. It's from a Marlin and it was left untreated)





At 6:00pm all the pieces were wiped down with a dry cloth, then sprayed with tap water and stuck in the fridge overnight (simulate condensation).



At 8:00am they were removed from the fridge.



They then sat out in the rain until 10:00am.

So Here's the results after 24 hours.




















I've now dried them off and left them in the basement to see what happens after a week.

Where is the cosmoline?
I mean, you already destroyed a barrel and all....
Even if it where a Savage..that's very Savage of you to have hacked it up

And no Fluid Film?

Sorry boys, only tried what I had on hand

Nice test. Reasonable methodology. Thanks for posting.

Conclusion: Nothing works except keeping your barrel dry and lightly lubed.

Correction; Stainless steel worked the best. ��

I wonder how motor oil would work

Good test, all I use is G96, looks like it held its own.

Hutning on the coast when you are in and out of boats in salt water can be rough on non stainless rifles, even using dedicated rust proofing gunk.

Thanks for posting your test and pictures. One thing that I've found lacking in the previous tests that I've read about is the use of bare steel as opposed to blued steel that we normally find on firearms. I'm glad to see the bluing on your barrels --- it'll be interesting to see if there's any difference in the amount of corrosion on the cut face vs. the blued sides.

There would be a difference even on uncoated steel. End face would have end grain exposed in the steel, generally a bit worse for corrosion.

Nice write up this far! Hope to hear back after the one week in the garage.
Was the stainless from a Marlin lever rifle?

Yes it is, from a 336xlr.

Marlin Stainless rifles are the only stainless rifles I've owned that have ever shown signs of rust. So I figured it'd be a good candidate for the test.
