Has anybody had any experience with Buffalo Bore ammunition? I finally bought my stainless .45-70 Marlin 1895GS recently, and I took it in to get a decelerator pad and different sights mounted. When I picked up the rifle, the gunsmith warned me against Buffalo Bore in stainless guide guns. He said he's seen ruptures (although the photos he showed me looked like the same gun) and theorized that it might've been related to stainless being a softer steel, or perhaps the stud for the magazine tube possibly being cut to deep.
I was surprised to hear this, as I've never heard anything negative about BB ammo. I've since done some digging online and haven't found anything about Marlins being damaged by it, either. Does anyone else have any insight or comment on this?
