Saw a professionally (and beautifully) done custom large-ring Mauser in a Mannlicher stock at a local gun store. The tag said .444 Marlin and I thought it was a mistake. But one look at the bore proved it wasn’t. The clerk on duty didn’t have any info on it.
A .444 Marlin in a quality bolt action intrigued me as a caster, but at $600, it’s an experience I’ll have to pass up.
