WW 2 .50 cal bullet cross section

[trailbiker]

Does anybody have any decent cross sectional drawings of WW 2 .50 cal bullets ? I've posted on here before about this (sometime ago) but didn't have much luck. The only drawing I do have has been photocopied and isn't particularly good.
I also would like to know how to tell the difference between an ordinary ball round and an armour piercing round when there's no paint mark on the tip to ID them ? Both would appear to have the same steel core, except the AP one is hardened alloy, apparently. Is there a weight difference ? Thanks.

Some WW2 U.S. .50 BMG:

Absolutely great, many thanks bdgreen, just what I was after !

Additional .50 (12.7x99) AP diagrams and sectioned .50 BMG projectiles plus information tables from TM 9-1990, SMALL ARMS AMMUNITION, 1947 (U.S.). Some of the images are sideways so download and rotate.

Great, thanks again, Brian. Can you tell me what the M1/M2 means ? Is that the type of weapon they were used in ?
I'm trying to find out if I can identify .50 bullets by their weight, as I have a lot from ground dug sites. Whilst I have a section 5 F.A.C, ID'ing them when the tip markings have disappeared is proving very difficult. Apart from the obvious double canulure ones which are locked away, the others are proving more tricky !! There's no telling what they could be.

The M1, M2 etc. designations for each of the projectiles or cartridge diagrams refers to the model number of the respective projectile (projectile diagram) or cartridge (cartridge diagram) and DO NOT denote the type of weapon they were fired in.

Note the projectile (bullet) weights given in the attached weights table (TM 9-1990, SMALL ARMS AMMUNITION, 1947), under the red star. I would bet most of what you will encounter are ball, AP & tracer.

Thanks, Brian. Just means the AP ones I'll have to keep locked up, providing I can ID them properly.
