Just a bullet question.....
Among some 9mm bullets I have some looks like the bullet itself were made from steel. I mean it looks like "steel plated" or something like that.....I have been told they wears the rifling very fast....is this correct. What are "steel" bullets made for? Thank you.

MIL ammo has been made out of many metals some aluminum case some steel case and most brass. Bullets also are made out of whats available but I suspect what you think is steel is really not steel . Is a magnet attracted to the bullet? or is it just silver in color? 0 -
Normally what you are seeing on the projectile from older 9mm Military ammo is NICKEL coated. Copper was evidently more expensive, and nickel, though much harder than copper is somewhat self lubricating which while not as desireable as copper, is still feasible in military weapons where tens of millions of rounds of ammo are produced at a time. To sum it up...econmy is the answere for why they used this stuff. I have a bunch of old 9mm Steyr ammo that is like that, and alot of 8mm Mauser that is the same.

breech, quickest way to tell is to use a magnet. If there is attraction, then it is either "steel" cored (often this is mild steel or iron) or jacketed. Take a rough file to a jacket. If the shavings / dust is attracted to the magnet, then you know for sure. Many military loads use a mild steel jacket. Even some US loadings from the WW2 era (although they have a thin coat of gilding metal on top to reduce wear) were steel jacketed. Steel is used for economic and strategic resource reasons. It is cheaper and in some parts of the world more easily procured than copper for alloys such as brass & gilding metal. Yes, steel jackets can be harder on a barrel than standard gilding metal.

Yes!....after filing it the chips are still atracted by a magnet. I was wondering how hard for the barrel is the round after continous firing. Are chrome lined bores beter for...I think.

I think if possible I would find some other ammo to shoot.But I don't know how much trouble it is to get ammo where you live. 0 -
The steel used is very soft, only slightly harder to engrave, and much less expensive than the standard "guilding metal" jackets.
The primary causes of throat/barrel damage/wear are sustained firing while hot, powder erosion in the throat, and poor cleaning technique/tools.
IMHO you will have to replace the barrel from throat erosion before you have to replace it due to rifling wear caused by steel jacketed bullets.

A 9mm-Steyr bullet I have is fully atracted by the magnet. Neither the other 9x19 rounds. This ammo was a military caliber as long as in Chile thousands of Roth-Steyr pistols were adopted as Army and Navy issued. Here I can buy any round for the guns I have (most 9mm) but paying some taxes for them.....Not cheap, but at least I can fire real and not Airsoft.......[:D]
