Could someone please explain what an "encapsulated base" bullet is?

Also, what is the advantage of an trancated cone, encap. base design? I see these two terms together often.

THANKS!

Encasulated base means that the base is has no exposed lead. That is significant for indoor range shooters in particular since some of the exposed lead is vapourised during firing. Encapsulating prevents this. Truncated cone (literally cut off cone) produces a flat surface that will to one degree or another replicate JHP feeding and punches very nice, distinct holes in paper targets. Those are good things for training. Combining the two features produces an excellent ammo choice for indoor training.

Then there is the designation, "TMJ", which I am told means total metal jacket. A synonym for encapsulated base, I would think.
Cordially, Jack

Correct in most cases, but it is possible to have a semi jacketed hollow point with an encapsulated base.

Which is what the WinClean uses......the BEB or Brass Enclosed Base with exposed lead nose. No pretense of expansion though. Acts like a jacketted hardcast SWC.
