I assembled 5 cartridges for a good friend who has a Model 94 made, according to the serial number, in 1946.
The load used new brass, 21.5 Gr Varget, WW LRP, and 117-gr cast that were provided by a kind member of the forum. I sent these off to New Mexico and he tested them this past weekend.
He reported nothing unusual *except* all the primers backed out a ways. Now I had hand-primed the cases, none of the pockets were loose, and all were seated just a hair below the case head. In other words, perfectly normal.
Any suggestions about the probable cause are appreciated. Note that I have no way of making a chamber cast since we're wildly separated.
He provided these images:
Thank you, Richard
