Which oil can / should / may one use to lubricate a semi-auto shotgun?

JM Browning is said to have used W30 motor oil. I know about a few instructors or top shooters who does it as well. I recall someone mentioning ATF too.

I have read about "dry oil" which apparently works great. I have also been warned not to use general purpose spray oil like Q20 because it dries  over time and collects dirt to form sludge.

This is made from what I had lying around, I did go buy the 1 meter lengths of steel tube, the endcaps for it and the 75mm square wood.

As close to nothing as you can get was my conclusion, the brass brush scrapes and scours the barrel clean down to a possible micro level. A good new brass brush will clean everything that matters out the barrel, there may be stains, molecular level deposits that only chemicals will remove, but as far as affecting your shooting level clean, a good few more than normal strokes with a brass brush will do it.

Fluid film
The original formula is (by volume) 3 parts Lanolin, 3 parts Mineral oil and 7 partsďz Mineral Spirits

I've never actually used it in the past.

Since I made up my own Ed's Red, I now know what it looks like - it looks like Ed's Red, but smells different.

Is it worth keeping ?

Anyone still using it to brush rifle bores ?

The zero group was terrible. From a half moa load to over four. I was, to say the least, very depressed.

This is the same day with the rude little c*nt on the range, so I was not in elevated spirits.

So I get home, and think about what I may have done wrong.

Now it just happened that next to me on the range that day was a young man whose rail worked loose, and he had come over to ask if I had tools, which I did, and helped him out with.

I thought about it a bit more, and realised that the problem has to be mechanical, not load related, because the rifle shoots anything to within one moa, which it did for me over and over during load development.

I rocked the scope from side to side, and the rail rocked with it. The front screws were loose, the one rear screw was loose, there was one tight rear screw holding the rail on.

In the past, I had used a clear epoxy to bed the rail. The Ed's Red contains acetone, and it penetrates between any metal surfaces. Some of it clearly found it's way into the the front chamber area, worked it's way up the front rail screw, into the second rail screw, and must have dissolved the release agent I used on the action when I bedded the rail, creating  enough of a gap to permit the screws to work loose under recoil. When I removed the rail, I had liquid between the rail and the front of the action.

I'm seriously considering using an acetone resistant epoxy to fix the rail to the action, after I get the rail screws bored out to one size bigger.

What a story. Cleaning is not just going through the motions with brush and solvent.

Firstly, nylon brushes are not for cleaning. They are for spreading copper solvent in the barrel. If you think you are cleaning with a nylon brush, you are in the category of "still have to".

Secondly, I think you should identify what the problem is. What needs to be cleaned is a function of what bullet material and what powder you use.

Are you cleaning lead deposits, moly, plastic, copper or carbon ?

Each one needs a different approach, and different solvents. There are some solvents that work better on one or the other, but none will be efficient for all.

And the bronze brush. The longer you hesitate to use it, the longer it takes to get the barrel clean.

You cannot wear steel with bronze. Yes, diamonds are cut with bronze blades. That argument is as logical as saying I've seen high speed water jets used to profile cut steel, so I should avoid getting the barrel wet.

You will not clean the barrel with a nylon brush. I got a reply to one of my posts on another forum from someone who claimed nylon brushes do clean because nylon wears steel. He once saw a boat propeller with a groove worn into it from nylon fishing line. I replied with my water cutting steel analogy.

Then there's the "my barrel shoots better dirty" school of thought. No, it doesn't shoot better dirty, all you've done is found the optimum seating depth for minimising barrel harmonics with that amount of fouling. When it fouls more, or when cleaned, the harmonics change, and accuracy is gone again. Basing accuracy on a particular degree of fouling - I think this is when people say "it took x number of shots for my barrel to stabilise after cleaning".  Yes, it clearly did, because you optimised the harmonics for a particular degree of fouling. It's as easy to optimise barrel accuracy for no fouling - keep it clean - then your baseline for accuracy is  always achievable without guessing, or wasting bullets.

I get the impression that people consider their barrels to be made of candy floss, and treat them accordingly. They fall into the "still have to" category.

And then the people who say they don't like to clean to factory new bare metal, so they leave it dirty. Here's a newsflash : once you start putting rounds down the tube, the molecular composition of the rifling in contact with the powder and the bullet is forever changed. You can never revert it back to "factory new", because "factory new" no longer exists, but you can clean it.

Here is some interesting reading to go with your barrel cleaning sessions :

Old school rifle cleaning.
