It's Mk. VII ammo, with a 174 grain steel cored boat tailed bullet. I believe the cases are copper plated steel. Berdan primed.
Does what it's meant to do, fires every time - and a hell of a lot cheaper than anything else out there. But, being boat tailed means if you've got a two grooved barrel on your Mk. I* she'll keyhole.
If it’s boat tail bullets it ain’t Mk VII ammo.
the brass has residual value (~ 50 cents a piece for boxer primed brass).
canada ammo has it for $20 a box
It's too bad that they aren't local to me. Couriers have historically lost everything that I've ordered.
I wonder if there's a way to ship it through the post?
