Justin,
Close, very close.
The LE127 is the prefix for their line of "tactical" slugs.
For 00buck they are:
LE132-xxx with the suffix designating 4B, 00 and 000 @ 1145fps.
H132: 1140fps
Intel6 is correct. The LE132's have hard-plated shot as opposed to the H132's non-plated shot.
I did some research on this a few days ago while hunting down shotshells to bring to the "combat" shotgun course. I decided to go with their P154 just because my local Wal-Mart had them in stock.
