DK - unless one has all of the box labels, which I do not, these Winchester Frangibles over the past five or ten years
are rather hard to sort out.
First, I have a .45 Gap Frangible, with the “W” bullet, but only in a factory dummy. The headstamp is WIN 45 G.A.P. I think that live rounds loaded later would probably have a headstamp of WIN NT 45 G.A.P. however. At a SHOT Show, I was lucky enough to get a dummy round for each fo the six Winchester Loadings of the time. Four are commercial, and I have all of those in live rounds also, but the two LE rounds I have never been able to find in live rounds. The Winchester LE Ammo Rep told me that he had never had one single inquiry from a California LE Agency about the .45 Gap, so he did not even bother to stock samples. The caliber never had any popularity to speak of with LE or civilians in our area. Of course, the cartridge is much ado about nothing, so that is no surprise.
Regarding 9 mm Para, I have the 100 grain frangible with its box. But, I have others as well:
WCC+P 04 Flat tip bullet, but no “W” on the tip. Cartridge weight: 158.3 grains (10.16 grams) Weight of pulled bullet: 90.5 grains (5.86 grams). This is Cartridge, 9MM Frangible, AA16, MK 254 MOD 0. I have the box.
WCC+P 05 Flat tip bullet with “W” on the meplat. Cartridge weight: 159.9 grains (10.34 grams). No box.
WIN NT 9MM +P Flat tip bullet with “W”. Cartridge weight: 168.5 grains (10.91 grams). Weight of bullet by box label: 100 grains. I have the box.
WIN NT 9MM +P+ Round nose bullet, no bullet markings. Cartridge weight: 151.2 grains (9.77 grams).
I also have the .45 ACP round, including box label: WIN NT .45 AUTO +P. 175 granin FP bullet with “W”.
Hope this is of some help, anyway.
