Great line. I used to use it as well.
I said, truthfully, that I would dispose of ammunition properly.
Amazing how many people are caught up in credential-ism and excessive fear of any stated risk, no matter how small.
Ammo, even that which is not waterproofed to milspec standards is rather , well, water proof.
I carry almost always, even canoeing and wade fishing- my carry ammo is not fancy, just plain JHP fodder, and I rotate it out into a “range box” after immersion. That ammo, about 200 rounds annually, has never failed to go bang.
I even did a test- river water and 50 rounds of ammo for varying periods of time- some in the sun, some ambient. None of it failed to fire and function perfectly.
As a mil type, I carried ammo immersed in swaps and torrential rain all in central and S America, never failed to fire.
Unless this ammo was immersed for months, it is useful as range ammo unless the firer is an idiot, probably not as carry ammo though.
Like I said, send it to me, I’ll dispose of it properly!
