well only two found. they are straight wall
2in long just a hair over 5mm.
mouth has a taper. more like a crimp then a taper in the wall.
base at just under .475in, 12mm.
groove at .400in, just a touch over 1mm.
case wall just about the groove is the same as the base.
tapers slightly down to about .450 in, 1.1? mm. about 1/2 in below the case mouth.
mouth with taper is 3.75in, .95 mm.
only id marks are "LC" "15" and what looks like a philips head of a screw.
the groove area looks like it has been through a lath. aka: recut.
in brass with boxer.
yes these have been shot.
best i can tell is a possible 38-55 winchester & ballard made for the early winchester 94 rifle.
to short for a 444 marlin, base to small for a 45-70.
anything???
