Strange primer ?????

[abunaitoo]

Found this 30.06 FR with a strange primer pocket.
It's larger than a large primer.
At first I thought it had some kind of pocket insert, but why would it????
Any ideas????

Not sure as to the why but they did use multiple primers sizes during that time frame. Had some GI 1940's era 45 ACP that used different sized than standard primers. I believe the groove is RA's method of crimping.

I believe that type of ammunition was designed to be fired in aircraft machine-guns. Maybe someone else can confirm this or prove me wrong.

The 45 primers were between a small primer and a large primer. That was so a pistol primer would not fit in the 3006. Have not seen this one before. I might be wrong and it is the way you showed?????

I compared it to two other cases.
It sure looked bigger.
So I tried fitting a primer in it.
It's just a large rifle primer after all.
Looks can be deceiving.

Yep, it’s a LR primer. I’ve got hundreds that I have loaded to m2 ball specs for the garand

I too heard that they were to prevent primer stoppages in aircraft machine guns but haven't taken the time to research it. It seems odd as I don't recall any U.S. fighter aircraft of that era that used 30 caliber. Possibly the 30 caliber was used in support aircraft of some sort.

Just off the top of my head as a start; the US Navy's Grumman TBF Avenger comes to mind - it had one 50BMG and Two .30 machine guns (one facing forward and one facing rearward). https://en.wikipedia.org/wiki/United_States_v._Miller

Douglas SBD 'Dauntless' gunners had twin .30 Brownings right up until they were phased out after the end of WW2. Ditto for nose turret of PBY 'Catalinas'. Army Air Force (AAF) also used .30 Brownings during early part of war...P-40B & C, and A-20A Havocs were both in service well into 1943. In addition, aerial gunners received much of their live-fire training using .30 Brownings.
