You mean ammonia is not corrosive to steel?
I don't pour it on, and I clean it right up. I believe it will take off bluing if allowed to sit. I also dilute mine substantially--1:5 ammonia to water.
I've seen plenty of people online who don't use ammonia. Some people claim pure water works fine. That puts me a bit on edge.
It seems opinions HOW to clean corrosive ammo varies widely, but everyone agrees that some sort of cleaning is necessary--granted, this vid was 2,200 rounds, but I'm all set with any rust and cleaning thoroughly if I shoot 22 rounds or 2,200.
Remember, the degree of rust will be dependent on how many rounds you shoot, how corrosive the ammo is, and how humid the air is in which your rifle is stored. The rust is caused not by the corrosive salts directly, but by the manner in which those salts draw the moisture out of the air and serve as an electrolyte for the chemical reaction of water and iron to bind for rust to form. To give you an example of how salt draws moisture out of the air, in addition to melting ice, road salt also works great in the summer to hold down dust of dirt roads. It does this by drawing moisture out of the air and dampening the dirt to keep the dust down. Or just think of how road salt or ocean water corrode boats and undercarriages if you fail to clean them.
I've used my ammonia mix as stated on my '31 Tula 91/30 Hex--which has a pristine bore. I've never had a problem and never intend to.
