@LouisIngenthron so apparently I've been doing some checking and modern day gunpowder residue isnt corrosive (except for blackpowder and blackpowder substitutes)... At least as far as I can see the idea that you should clean it after every shooting session is a bit out dated.
@freemo There are a lot of factors, like whether you're using new ammo or reloads, how many you put through it in a session, etc.
If you're shooting two days in a row, do you need to clean in between? Probably not. But it's still good advice not to leave guns dirty for extended periods of time, and to err on the side of safety, as regular cleaning is necessary to the upkeep of any mechanical device, but that goes double for devices meant to regularly contain explosions without breaking.
@freemo There's probably no harm in that strategy.
But I would put it to you: If, god forbid, you found yourself in a situation where you needed to use a gun to defend your life, would you prefer to use one caked with soot, or one that's been cleaned and oiled?
The men who keep coming for James Bond know the value of a good mirror sheen on their rifled barrels.
@freemo It depends on the ammo you use. My .45 long colt weapons are caked with soot after one shot, but firing new 9mm rounds tends to be considerably cleaner.
You got a gun in chrome, right? Should be pretty easy to see. I'd expect visible soot in the receiver and barrel within 100 rounds. And for the guns you can't see it (i.e. black metal), you can smell it. Like rotten eggs.
@LouisIngenthron Thats fair, I will admit my 0.45 long builds up soot quicker too.. might go a few hundred rounds before it gets caked up. So adjusting it on a per-gun basis makes sense... I still wouldnt personally clean it before the soot becomes noticable.
I do not have a gun in chrome. one has a black finish, the other a nickle titanium finish, and the judge im not sure what finish that has, might just be plain steel.
@LouisIngenthron cleaned and oiled.. but i dont think it would be "caked with soot" if its cleaning was less than 1000 shots ago either.
