Probably one of those rare 1919A4 chambered for 30-40 Krag. Just to use up surplus ammo from the Spanish American war. Actually the ammo technical manuals from 1947 still mention 30-40 Krag ammo. It was used in a sub caliber set up for artillery. Maybe that was the only ammo they had for the photo op. The M1925 sub-caliber 30-40 cartridge did have the pointed bullet just like in the photo.BTW, is it just the light in the 1919 pix (third one down) or are those rimmed cartridges in the belt?
Only the cartridge case was 30-40 Krag. The bullet was pointed like the .30-06. I have found that the M1925 sub caliber round was intended to be fired from the 3 inch seacoast gun. The muzzle velocity was 1,990 fps Max range 4,300 yards. The cartridge was 3.19 inches long. The TM says "the bullet used is the M1 .30 caliber ball bullet formerly used in .30 caliber rifles and machine gun cartridges". The bullet weight was 172 grains. There were older .30-40 cartridges used for the same purpose that had the older round nose bullet and were known as "cartridge sub caliber , cal .30 OLD STOCK" The round nose bullet weight was 220 grains.My take is this. Brand spanking new 30-06 with turned rimbase = shiny as heck. Optical illusion. The original AP 30-06 we got years ago from SOG was seated like this, ALL the way in! Also, that looks like the M1 ball bullet to me , not a .30 krag pill. Plus the belt is filthy and probably as loose as a sixth-year sorority girl. I do like the azimuth ring tripod. Very nice. J
Most look staged to me, especially the ones with men on the edges shouting instruction or laughing their butts off. On one end of the spectrum you have the lady with the carbine who obviously knows what she is doing. On the other you have the lady "sighting in" the 1919 with a loaded belt in place, her finger on the trigger, and her face about 1/4" from the back plate. That's gonna leave a mark.
In my platoon of 41 MP's, Ive got several small females and a half dozen guys under 150 LBS. ALL of them can charge a M2, ground mounted, in less than 3 seconds.An M2 was never designed for a woman or a whimp and takes considerable physical force to charge it. Without instruction, it appears to be a top grip. Yet a bottom grip yields better center mass ergonomics overcoming counter force.
