Is 7n6 armor piercing?

[djturnz]

"The basic ball projectile (Russian military nomenclature 7N6) has a gilding
metal clad mild steel jacket. *I*nside the jacket is a lead sheath, which in
turn surrounds a 15mm long mild-steel core. The mild steel core's base is
mounted at the base of the bullet jacket. At the steel core's nose is a 3mm
long lead plug which is actually an extension of the lead sheath. In front
of the lead plug is an air space approximately 5mm long. By placing the
projectile's center of gravity toward the rear, the design team virtually
ensured that it would tumble end over end when it struck a human body: When
the bullet strikes a target hard enough to deform its nose, the hollow
cavity is crushed, and the center of gravity changes rapidly, causing the
projectile to upset and tumble."

5.45 ammo. With the mild steel core, is this stuff safe to use on a metal gong target?

probably not, just due to speed... mild steel still makes a hole, and resistes deforming MUCH more than lead or copper.

i wouldn't, unless the gongs are DEFINITELY Armor with at least a 500 brinnell hardness.

Not sure what your criteria for "safe" is, but:

• 7N22 is the designations for armor piercing 5.45mmx39
• 5N7 & 7N6 has a steel core that will gouge the gongs.

depends what the metal type in the target is.
i shoot steel with that stuff all the time, doesn't hardly even make a mark on the target.
but it does make a bunch of these.
it's a penetrator type round as in body armour, nothing anything more than a "normal" round on steel.
