Cleaning guns after using ammo with corrosive Primers

Post by **Mack The Knife** » Wed Jan 28, 2009 10:19 pm

AMK,

Whilst corressponding with Grumpy yesterday on this very same topic, Grumpy mentioned that he is very happy with Tetra's bore solvent. It then occured to me that there was a supplier for Tetra Gun Cleaning products in Calcutta. I looked it up on the net and came across an R K Trading Company - http://www.seekandsource.com/category/d ... plies.html

I have sent them an e-mail but have yet to hear from them. If any Calcuttan reading this could look up their address and phone number and post it here, I would be much obliged.

It's not the smokeless powder that is corrosive, but the primers. If there is any doubt about the primers being corrosive at all, clean immediately after firing with hot, soapy water and a soft brush, then dry and oil. In a dry desert climate corrosive primers are not that much of a worry, but under humid conditions corrosive primers will rust a barrel within hours. Hoppe's No.9 is a powder residue solvent, it does not help if primers are corrosive. Ammonia removes copper fouling. If you want to check if your rimfire ammo has corrosive primers, pull the bullet and dump the powder, then fire the primed case against a polished flat piece of steel, with muzzle a few inches from the plate. Leave it exposed, if it rusts, it's corrosive. Cheers.

Two Rivers has good advise.
I would reccomend spraying a good window cleaning liquid like Windex or something prior to the Hot soapy water and hot water treatment.

The water should be as hot as possible...
Also please do ensure that the bore is completely dry before oiling. Bores, can and do rust under a layer of oil.
Dont ask me how I know.

Thanks Mack The Knife and everyone else.

My friends visit Kolkatta often so I'll ask them to get some Tetra and I'll try it. For now my bore is fine as I haven't fired much, if need be I'll use the Hoppes Nitrous Solvent Bore cleaner. I'll also try ammonia but if I'm not mistaken ammonia can be a little dangerous if not diluted? If I get over my laziness I'll also try to make some Ed's Red.

The breakfree CLP I have does a decent job of oiling and general cleaning but I agree with Penpusher; hot water is the ultimate when you don't have access to the specialised solvents.

Keep other suggestions coming and the discussion open meanwhile.

AMK

From what I have been reading on the net, ammonia is hygroscopic and a 10% or stronger solution of ammonia will result in rusting.

No rust so far.Amonia is easier to get out than salts deposited by corrosive primers.Run a couple of patches till the barrel is dry.Plain hot water is what was and still is used for the Enfield 303 rifles.

There is a fancy funnel for sale by Kynoch for this purpose.

Ammonia will also take off stock finish.
