I'm looking for a comprehensive list of variations of MIL 5.56X45 NATO. M193, M855, M855A1, etc.

MIL only, not civilian versions.

Thanks!

The M196 tracer cartridge (54-grain bullet) 5.56×45mm NATO was developed for the original M16 rifle and is compatible with the M16A1 barrel also using 1:12 rifling twist.

The M856 tracer cartridge (63.7-grain bullet) is used in the M16A2/3/4, M4-series, and M249 weapons (among other 5.56mm NATO weapons). This round is designed to trace out to 875 yards and has an orange tip color, and is trajectory matched to the M855 (62-grain, green tip) ball cartridge.

MK262 and MK318

Wiki lists them all, there are many more than you would think. Dozens if not over a hundred.

M193
M196
M199
M200
M855A1
M856
M862
M995
M996
Mk 262
Mk 318

Eta: Not a complete list, I'm certain.

M193 55gr Ball
M195 Grenade Launching
M196 Tracer (red tipped)

M862 Short Range Training Ammunition (SRTA, brown tipped)

There's also 70gr Barnes TSX and a 200 100gr powdered frangible that I had in Astan.

Only 3 loads I haven't seen are the M195, M996 and proof rounds

Thanks CD!

Thanks!

There is 5.56 and there is 5.56 NATO.  M193 and all the stuff that was intended for the A1 was not NATO ammo. M855 was however.

200gr frangible?

Nope, miss type as I believe it was 100gr
