Just me, if I know I aint gonna have time to clean it, I’m not gonna take the time to dirty it. But, at the same time, I've shot corrosive for close to 20 years, and not once have I had a barrel fall off, not once, has a gas piston seized, not once, has a bolt turned to dust, not once, have I found rust. I can not imagine firing any number of rounds of any ammo and just chucking it in a closet, safe what have you. You invite in the "H" factor, or the "h"uman factor, the "oh, I'll clean it tomorrow", and suddenly tomorrow turns in to a week, a month. Yes, I know it comes out sounding like a dick, but, it is what it is, an excuse. And, yes, I know all too well what it's like to have a drop what your doing and go to work job.
Again, it's just ramblings from someone who doesn't put any value on the corrosive/non corrosive bit. Too each their own, sorry I even said anything
