I highly doubt it. The loading gate appears way too short....and that's a SilencerCo Osprey on the end of it. If he's pushing .45-70 out of his Osprey, well, let's just say GLWS. I've got a Scorpian 458 can that is still unfired because I have yet to find the right host...so sorry for jumping on it like that. A suppressed .45-70 is my next project.Interesting. The guy who posted it said it was a 45/70. Maybe it really wasn't his pic......
