Arthur's weird glitches for Sharpshooter 6 in Red Dead Redemption 2

Here's a reasonably reliable way to get Lenny's Rolling Block rifle using the companion glitch. It still takes a few attempts, though. You can do it much easier with Hosea in the beginning of Chapter 2, but not after the Exit Pursued by a Bruised Ego mission. If you've already done that, then this method is better than restarting Chapter 2.

As a bonus I show you another way to get the Rolling Block from Hosea without using the companion glitch, so you don't need to blow up Arthur. You can only do this in the beginning of Chapter 2, though. It may not work on consoles, I've only tested it on PC.

You need the Rolling Block rifle to do Sharpshooter 6, but you don't normally get the rifle until The Sheep and the Goats at the end of Chapter 2. To trigger that you would also need to catch TB from Thomas Downes and free Micah.
