Yeah you are looking for the old outdated US 55gr 5.56 round and not the current 5.56 Nato round. When they went from the a1 with teh 1 in 12 twist to the 1 in 9 twist they canged the lloading to teh steel stuff that FN designed. I bought a case of Silver Bear 62gr softpoint a few months back through cheaperthandirt. I think tis gone up since then but the silver bear stuff is the way to go. It doenst have the laquer case that gums up ar systems like the wolf or barnaul shit does. Its zinc plated instead, and yeah its steel and steel is supposed to wear out extractors faster but it a part that cost a few bucks to replace and you save a ton in ammo. I have never had one problem with the steel shit in any of my pistols or rifles, although I hear they are hardest on 1911's. I find that odd since TOkarevs are pretty much a colt copy and they eat steel all day long.
