Took the Ruger Super Redhawk .454 Casull to the range yesterday. I happened to have the trusty Flip Video camcorder with me, so I loaded up one round of .45 Colt and one of .454 Casull and let fly.
Here is the gun:
And here is the video of the recoil differences firing one handed:
MI2Tall fired 2 rounds, and while he did not find recoil intolerable, his middle knuckle got beat by the back of the trigger guard. He liked the .45 Colt loads, though.
I have a couple of vids on MI2Tall firing the Scoped Marlin .44Mag that I'll try and upload later.
