Is this a new bench rest cartridge?

[labgrade]

Ran across one piece of brass today at the range.

Headstamp is Lapua .308 WIN ... I'm OK so far. That's where it is parts company with .308 Win.

OAL = 1.850" (SAAMI specs for .308 Win = 2.015")
shoulder angle looks to be right at 60 degrees ("measured" with a 7X hand loupe w/angluar marks) = very sharp (.308 Win = 20 deg)

"Obvious" wildcat & whomever loaded this had placed a Sharpie pen index mark & a # for tracking.

Looks to be an attempt at a sorta PPC-type cartridge but in .30 cal

Any ideas?

Too, Harley/mods, if this isn't the right place, feel free to move to whatever topic area ....

Proper Forum???

labgrade,
This one deals with such an overlap area that I don't believe any of the moderators will fight over where it belongs. I wouldn't worry if you'd posted it in "my" Handloading & Reloading area, and it would seem to be at home in Art of the Rifle. Equally, it is an area of Research, and I imagine Harley will tolerate it pretty well right where we are.

(And it could well be some sorta new handgun round--Even a revolver sorta thing: Let's see, how 'bout some full-moon clips to use it in a long-cylinder Super Redhawk?)

(Or, or, uh, in Full Auto. Yeah, that's the ticket: In FULL AUTO FORUM! Think carefully, now--Were there M-60 links in the area where you found the case?)

Hummm--Probably not in Shotgun though. Nor in Cowboy Action Shooting, or the Close Quarter Battle vicinity.

Just thinkin' out loud.

Best,
Johnny

Johnny, that's why we need a new forum for weird stuff we've picked up at the range. Ahahahaha My next request, soon as the darned magazine's named.

Think I'll let this sit for a couple more here & if nobody picks up on it, I'll spam the other forums - see what turns up.

Talked to this guy at the range who had built 2X BR rifles based on a sorta .22 & 6mm PPC 'cept its parent case was .473" rather than the .22 Russian's .441" - get to use standard bolt face, etc.
... cute li'l things.

Found this .308-based case after he left ... bet he could've shed some light on it. These bench rest guys come up with very interesting (& super accurate) stuff!
