is is.
I wouldn't say really old, the h-322 is late 80's, and the others are mid-late 90's.
that's the same 748 cans I just used in the XCB rifle to shoot those groups in the range report thread.
I cut the label off one can, dumped all mine together in a plastic jug, then taped the label on the jug and shook it all up.
stuff meters like water though.
that 4895 if it's like mine in the big metal can is pretty fast.
it's quite a bit faster than the IMR I have that's newer stuff.
like close to 3031 fast in some applications.
