Registered Users do not see the above ad.

What about when the bolt closes and the extractors have to open and then close as they snap over the cartridge case rim? That's got to be hard on the extractors.
I wish I could be half the man my dog thinks I am.

It depends on what kind of extractor and how it works, but they are all either a spring themselves or spring temper steel operated by another spring. The angle on the very edge of the rim of the case can cause more problems than what the case is made of. Think of how many times an hour your car's valves rub on the cam or how a starter gear engages the flywheel. Properly heat-treated steel can cycle many thousands of times even without proper lubrication.

Extractors are designed and made to last thousands and thousands of rounds. I've run thousands of rounds through my pistols without ever needing to replace an extractor. Steel cases are likely to be softer than extractors in order not to shorten their lifespan. I'd guess few of us on this site have ever had to replace an extractor. Gun designer/engineers, especially the Russians, know this when they write the specs for this part. Just my dos centavos. YMMV

The steel has to be very soft, otherwise it would be a real booger to form into a case... think about it....

Yes, i pointed out what you say. The steel used in the cases is a mild steel however, some have reported excessive extractor wear after a number of rounds which vary but seems to be 500-1,000 and up. Considering the price of an extractor and the cost savings of steel v brass ammo it can save you money.

I have some in spam cans I bought to keep on a shelf just to have a few thousand rounds on hand. I shoot up some 9mm and 45acp steel on an infrequent basis but since I reload it is not a normal thing for me. I have not noticed any excessive wear yet but that is just my guns.

Personally, if money was tight I'd do it and not worry but a better bet is that if money is tight, save and buy reloading equipment to load your own brass and leave the steel for others.

I also reload and my cost of brass over the years is virtually nothing. I am a brass scavenger and not adverse to asking the shooters next to me if they intend to retrieve their brass that's laying all over the shooting line floor. Shooters who leave lots of brass on the ground while shooting tend not to be reloaders and in most cases gladly tell me to I can have their brass. The only factory ammunition I buy is .22 LR, everything else I shoot is reloads using factory or home cast components. Hence, everything I shoot be it handgun or rifle is reloaded in brass. YMMV
