I just unloaded my home defense shotgun for its bi annual cleaning. I noticed the crimps on the shells is folding inward on several shells, Should I be worried about these shells having too much pressure? They are Remington Express 0 buck 12 pellet load and have been in there some time. I don't like throwing useful ammo away so if these are still good I will keep em, just no loaded in my home defense shotgun.

SHOOT IT!!!!!

It is not loaded with unobtanium - SHOOT IT UP next time you go to the range and reload it with fresh ammo. One of the reasons I am so militant about people not using SUPER SPECIAL ammo in their defensive shotgun is that people are reluctant to shoot expensive ammo and replace it as often as they need to. Shoot the gun, shoot the ammo you plan to use if you ever have to use it for real, and know what YOUR gun will do with the ammo you use at various ranges. This is critical knowledge and the only way to know is to go shoot it. Your biannual cleaning should come after a range session!

Remember what Dave always said - BUY AMMO, USE UP, REPEAT. Even in these times of a constricted supply chain, there's buckshot available if only by Internet order.

As long as the crimp is holding the shot in the shell its doing its job. Absolutely nothing to worry about, the round will work as well as any.

If you mean the petals are dished in, no problem. If you mean the top is crushed inward. No problem. The wads have "legs" between the shot cup and the base of the wad which absorb any "crushing". The powder is already compressed as much as it will get so there isn't any setback effect like on metallic loads.

As Fred said SHOOT IT. Then go out and get some fresh rounds and shoot some more.

was worried it would be unsafe, like compressing the powder or some such something.

Its not super special or expensive. I unload the gun to go shooting once every month or so and just throw whats in it on the bed. Then reload that back when I get home. I actually shoot the gun about twice a month and usually run a box or two of the stuff to make sure I know what I am doing. But I usually only run a rag over it and some light oil. This gun really doesn't need cleaning much to work, just a little oil.

Actually crimp depth does affect pressures in shotshells. If using maximum loads a deep crimp will put the load over max.

Take that ammo to the range, and shoot it, then load the gun with new ammo when you get home. I doubt the inverted crimps will cause problems, some of the stuff Hornady was turning out a couple of years ago (TAP) was crimped so bad I quit buying it, but there was never any problem shooting it.

There shouldn't be any problems with the ammo as long as the "damage" doesn't add resistance to the opening of the crimp like deliberate depth or improper loading tool adjustment does.
