Default Steel cases vs. brass or aluminum?

Why does my LCP say to use brass or aluminum casings only? What's the difference? Does the steel create higher pressures? Did the 59 steel cases I ran thru it do some sort of damage? What about the other 441 rds I plan on useing?

Thanks for the coming info!

Brass and aluminum are more maliable than steel. Steel casings will prematurely wear the chambers and the headspacing in the cylinder. When the round is fired the gases expand the casing to form to walls of the chamber gripping inside of the chamber walls. This is less so with steel casings and will cause excess pressure on the firing pin bushing from the casing head being pushed back into it with excessive force.
I dont know of much 38 or 357 ammo that is steel cased. What brand of ammo are you using?

Start slamming too hammers into each others and see how long they last. Next take a sheet of brass and start beating it with a hammer and see how long the hammer lasts. Plus do to the stiffness of the steel the cases don't seal the chamber as well causing you to have to clean more. Cleaning more is not fun.....

Default Ive used it all

I cant say that I blame you for using steel cased ammo for your LCP. Its a 380 and those are expensive to shoot, I got rid of one for half of that reason. The other half was it didnt want shoot hp ammo.
Your question: I have shot from cheap to terribly expensive ammo in my guns(ruger p95, sr9c). They all still shoot and I cant imagine your lcp being damaged by the small amount of steel cased ammo youve used. Im sure that theres reasons why some say not to shoot them(post above), but if its what you can afford Im sure your practice is more important than the tiny amount of damage done. MAYBE after a few thousand rds you might start having problems, MIGHT. I have complete faith in Ruger though.

Think of the case as a gasket. It is designed to expand and seal off the chamber preventing high pressure gasses from excaping to the rear where your face is. Steel cases do not seal off as well as brass or aluminum.

Steel is fine in the pronounced tapered applications like the Russian 7.62's but is a poor choice in a straight walled case like the .380.

Thanks for the info guys...I will go ahead and use up the ammo I just bought before switching.

Do any of you have a recommendation for a bulk ammo source in brass or aluminum?
