Irregarless of what my good friend John, has to say… I’m no expert in anything, except in goofing off and screwing up, but I’ll try to help.
It also amazes me that the NATEC site is still up. The last I had heard was that the facility had closed and was either in bankruptcy or receivership. Prior to that in late 2004, they were closed for reorganization, hoping for some overseas investors to step in.
To try and answer “hwbx’s” questions: The colors used by NATEC have been a question of contention from day one. Were they ever going to indicate a loading by the case color. For loaded ammunition this seems to bear fact, but with dummies, it seems that almost any thing goes. One other item that has not been constant are the mold numbers on the sides of the cases. The mold mumbers of 1 thru 8, appear on most loaded rounds, but not on all.
Why, who knows, we may never know.
Here in a what I have in regards to the four NATEC PCA items listed in the orginal post by “hwbx”
H/S: 223 REM PCA 03 Black case 69 gr Sierra Matchking #PC22369M
H/S: 223 REM PCA Green case 55 gr. Sierra Blitz # PC22355B
H/S: 223 REM PCA 04 Red case, 55 gr. tracer #PC22355RT
H/S: 223 REM PCA Tan cace, fmj 55 gr. fmjbt #PC22355F
Note: the 55 gr. fmjbt # PC22355F also appears in a grey case body
Note: the 55 gr. tracer # PC22355RT appears with and without a red tip ID
