Also came across some good info awhile ago that I forgot ALL about. Some good options from Federal, all being .223 loadings in PDF form.
Hopefully that link works. If not, google "Federal .223 wound characteristics", it'll be the second result (PDF). I think the LE223T3 is the same, or basically same as the "TBBC". I was interested in the T223L TRU 64gr round a long time ago. Great performance in bare gel and most barriers, except glass.
