I'm assuming that since steel is generally harder than copper that it will cause extra wear and tear on the barrel. is this true? is it enough to worry about? does steel jacketed perform differently on/in a target? better or worse penetration etc?

edit to fix typo

There definitely will be less bullet deformation/fragmentation, which in turn will cause deeper penetration. I am pretty sure that it will cause accelerated weapons wear. I wouldn't use it. O.k., o.k., I've used the bi-metal ruskie crap in my sten but I got about 5 extra tubes for it and I got the bad one in it now, so I don't care about the steel jacketing wearing it more (maybey it'll smooth out the roughness) I wouldn't use it in my ar's though, but that's just my opinion.

I've never seen a steel jacketed rd. I've seen steel cased rds. Someone tell me what I'm missing?

Most Norma commercial ammo had steel jacketed bullets. Few diss Norma ammo for that reason. I certainly don't...

Much surplus ammo has steel jacketed bullets (for example, the Portuguese 7.62x51mm NATO ball has a steel jacket under the copper flashing..). Most of the mild steel jackets won't wear the barrel any faster than guilding metal jackets...

just used a magnet on the turkish surplus 8mm I got today. the sign was right, it's steel jacketed.
not worried about the extra barrel wear though as I won't be shooting it very often

Hate to tell you guys, but both the turkish (1947 ans '39 stuff) and the norma commercial stuff is CUPRO-NICKEL, it's silver, but it's NOT steel. I've shot vast quantities of both, and in my job I work with a LOT of cupro-nickel piping (magnets try to stick to it too) Portugese ball, shouldn'r have copper washed steel jackets, but some of the armor piercing stuff does though.

I agree. Steel core perhaps but not a steel jacket.

Most US GI .30 caliber and 7.62mm ammunition made since 1968 has had copper washed steel jacketed bullets. It is a mild steel that shoudn't contribute much, if any, more to barrel wear than copper jackets.
