since i suck at explaining this in twitch chat, have a video in horrible quality

you can get rapidfire by having your gun in your hand, jumping and spamming the weapon wheel & dead eye buttons (L1 & R3 on Ps3), you'll hear the dead eye sound and or see the screen colour change.

no rolling around.

also same thing works while riding, move, jump, spam weapon wheel & dead eye

Oh hey sweet, thanks! I knew and use the horse jumping one, but I didn't realise you could do it on foot too. Also interesting that you can do it with Revolver, that can be useful in a few missions.

EDIT: Upon further testing, it seems that this super simple method actually works with EVERY gun! My previous on foot rolling method never worked with anything other than Repeaters. I need to think about using this glitch everywhere now

So I've been trying to figure this out and I'm getting no where, is it really just jumping with gun out and mashing LB and R3? Does this work on Xbox? Am I missing something obvious?

Edit: Oh, I just read the other thread about uninstalling the patches first. Its super easy now, derp.
