Very nice find, most of them I've seen in the wild are pretty beat up, usually with cracked wood.
They're a neat looking thing, but I shot one in 30 and found it downright unpleasant for such a small cartridge. I can't imagine 300 being very much fun at all. If I ever came across an 8 in 25 for the right price I'd probably snag it, but the odds of that are slim to none with rifle prices being what they are these days.
