I was thinking about the 38 spl158LSWCHP+P+ when I wrote that. A few years ago I read an article about movement of ammo in mag, from being carried in mag holder, pocket. Supposedly the constant movement of the body "could " cause some shifting? Did not believe it but decided I would look at my mags, and found one where the cartridges appeared stuck 4th round down. Was this from movement or incorrect loading by me?? I cleaned, marked the mag, reloaded it and carried it multiple ways, fanny pack, pocket, briefcase, backpack, etc. I have never found another mag that shifted, and the one that I "carried" never shifted, so maybe there is no need to reload mags every month. I have just gotten into the habit of doing it, much like looking at every round before it goes into a mag, since I have found some factory ammo with damaged, deformed cases new out of the box. I notified companies about it. Be Safe,

I BACK OUR BLUE

I was taking a firearms course back in the 90s at a police range. The instructor was the rangemaster. He related an interesting anectode. Somewhat related. Back when LAPD issued the Beretta 92, their motorcycle officers had an unusual problem. 92 mags have a little crease on each side where it transitions from double-stack to the feed lips. Apparently, the vibrations from riding the motorcycles caused the rounds to rotate inside the mags, scoring the cases. They had case failures when the rounds were fired. Motor officers were instructed to inspect and replace the rounds in their mags regularly.

In my 60 plus years of shooting everything you can name, I have had exactly three cartridges fail to fire; A soggy paper shotgun shell, a .22 LR without priming compound, and a .45 ACP that I thoroughly fouled with resizing lube. My expectations remain unchanged. The only reason I can think of to fiddle with cartridges or magazines is to make sure that the first one in a magazine stack has not corroded and stuck to the feed lips.

If I take an EDC or HDG to the range then I'll use up it's ammunition and load newer ammunition. Otherwise, I just leave it all in there because I don't worry about its age. I have dated factory ammo from WAY back, dates that I wrote down on the boxes - it all shoots just fine.

My practice has been to shoot up my carry ammo every 6 months and replace it with fresh ammo. Never had a problem doing that until the last 10 years or so of political nonsense driving the ammo business into the ground.

While I used to purchase a couple of boxes of fresh factory carry ammo routinely, once per year or so, now I purchase a case at a time and that will keep me going for 10 years at a time.

I still try to shoot every week. I still "roll my own" reloads with home-made cast bullets, and I load most handgun calibers by the thousand at a time. No substitute for regular practice.
