Tachead, you have single handidly convinced me to run steel cased, copper plated steel projectiles in my ATRS AR. 1000 rounds at least on the first range visit. My poor dillon is going to be sad I didn't load my first 1000 on it!
I meant if you only shot 50 rounds of corrosive you would still have to do a full disassembly and cleaning when you got home. I shoot hundreds of rounds in my SKS and only clean when I get home as well. I didnt mean you would have to replace your gun all the time. I meant that shooting steel case/steel jacket could cause more wear in turn wearing your guns out faster. Thats all. And thats fine if you dont agree with it. Do whatever you want with you firearms. I just dont shoot it in my high end ones because of the risks I outlined.

Tachead said:I never fire MFS in my firearms. Some of it uses a copper plated steel jacket on the bullet I hear.
FYI, The MFS sold commonly in Canada is actually Russian made by Barnaul. It is not made at the MFS plant in Sirok, Hungary. Last I checked they were bimetal jackets.Maybe you should rely on real facts instead of something your heard. First off, taking a look at MFS website, you would have noticed that jacket material listed for every single cartridge they manufacture is CuZn10 (#C22000) which is commercial bronze guilding material. There is NO STEEL in it, 90% COPPER, remainder ZINC.
As per being described as a self proclaimed engineer, I'm totally speechless. Needless to say that you do not have a clue of what you just meant and how insulting it can be.

Threads like this are not about opinion, they're about information. A lot of people can't tell the difference between their opinions, and actual information.
So thankfully there is a fair amount of actual information in this thread. The reason I am hard on guys like Tachead is that some new guy is going to search "steel cased ammo" before firing it in his gun, find this thread, and not know enough to be able to tell who knows the subject and who doesn't.
It's pure luck that we got a couple of guys with massive credentials to step up and explain the reality of the situation, so hopefully anybody who stumbles across this thread down the road will not get confused by the argument.
