Grip it and rip it.
okay, seriously - I have a .480 Ruger in the Super Redhawk. Not quite as hard kicking as some revos, but when I am planning to shoot it I'll usually wear PAST gloves to take some sting out of the hand.
For accurate handloads, whatever bullet you're using, in a straight wall magnum revolver case, I turn down the expander plug down until it's at least .005 to .007" smaller than bullet diameter, to get a tight bullet fit. I then seat the bullet and apply a heavy crimp. This step assures best consistency and prevents the recoil from pulling bullets. I like Redding Competition Handgun seating dies, or Hornadys if I can't get the Reddings.
I like Lil-Gun for magnum loads, but there are other powders that work well, too.
Congrats on the FA, they are beautifully made, regardless of how hot you load them.
