Found this on YT while looking for some videos on the 1873.
First odd thing is that he says that because the Winchester is a tube fed and also the recoil, that straight wall cartridges, like the .45 Colt, can push the bullet deep into the case causing all sorts of problems.
Then he says that with the Henry that if you feed rounds into the tube with the rifle straight up, you can cause an "explosion"!
I guess he means that you'll detonate the rounds with them hitting the primers.
Usually, Shooting USA puts out good videos, but this one makes me scratch my head!
I've never heard these claims before.
