It could very well be tungsten, we were told Teflon. I have never researched to find out.
Well, I did because I have quite a few of them. Speer
used to make what its own reloading manual called a "duplicate" of the M 855 / SS 109 projectile and I ordered some to see if it was true. Back in '94, when I first ordered the Speer bullets, I was trying to figure out a way to determine if the penetrator was there without destroying the bullet.
The material on that ammo referred to a
steel penetrator. The magnetic screwdrivers hanging from my reloading cabinet provided the obvious answer. Swiping them across the bullets made the tips, but NOT the bases move, proving that they had the steel penetrator. Barnaul bullets, which have no penetrator but a mild steel jacket under heavy copper plating, move wherever the magnet is placed.
As neither tungsten nor titanium is magnetic, it would appear that neither is what the penetrator is made of. It must be steel and cannot be Teflon. Indeed, you are the
only person I've ever heard say Teflon was part of mil-spec rifle ammo.
NOTE: Speer subsequently stopped inserting the penetrator, thus changing the bullet length, but did
not change the part number. I found this out when a later batch did not seat properly. Subsequent testing showed NO magnetism; this and the shorter OAL proved the absence of the penetrator. I started buying IMI bullets instead, as those are still correct.
As FAR as Capitals, I use them to ACCENT and sorry you feel it is rampant. I wasn't writing to please you but put out info, It seems you are more interested in finding fault than gaining info.
I never said your use of them was "rampant." Further, ACCENT is fine; Random use for No discernible purpose is distracting.
