Ah gotcha. Yeah Matt and Nate are good guys. I just figured maybe they'd know somebody. Not sure who else to check with honestly that I'd have confidence in.
The guys at Howard's Pawn are pretty knowledgeable. And they have a decent amount of local connections with other gun experts from my experience that they could possibly point you to.
I've been out of the 8mm Mauser game for awhile so I didn't realize how hard it was to find ammo for it now. I remember being able to buy it at pretty much any sporting goods store that sold ammo. I used to buy the old Winchester Super X all the time.
