F A 49 CARTRIDGE CAL. .30 ( PRIMER T53 ) PRIMED CASES
PLEASE FOLLOW THIS LINK TO VIEW THREE ( 3 ) DIGITAL PHOTOGRAPHS OF THESE PRIMED CASES:
I’ve had these sixty (60) March 1949 Frankford Arsenal caliber .30 (.30-06) “T53” primed cartridge cases for more than forty (40) years, but I’ve never been able to find out any definitive information about their “T53” primers. I know that Frankford Arsenal experimented with various non-corrosive primer mixtures sometime after World War II, and I believe that Frankford Arsenal standardized a non-corrosive lead styphnate primer mixture for all of its standard military caliber .30 (.30-06) ammunition sometime during August of 1949.
I also know that sometime during 1949, Frankford Arsenal experimented with a non-corrosive primer mixture consisting of barium nitrate and red phosphorous. Additionally, I know that the copper cups of those primers were zinc plated, and that when those primers were used in caliber .30 (.30-06) ammunition, a plastic disc that was placed between each primer’s anvil and the bottom of each cartridge case’s primer pocket, covering each primer pocket’s flash hole.
The “T53” primers in these March 1949 Frankford Arsenal caliber .30 (.30-06) cartridge cases ARE NOT crimped, they DO HAVE the standard military red lacquer sealer, their cups DO APPEAR to be zinc plated, and they DO NOT APPEAR to have any plastic discs between their anvils and the bottoms of their cases’ primer pockets and covering their primer pockets’ flash holes. So, are the “T53” primers in these March 1949 Frankford Arsenal caliber .30 (.30-06) cartridge cases non-corrosive and made with a lead styphnate mixture?
Thanks in advance for your answer(s).
