45Man the 405gr RHO (Red Hawk Only) is a 405gr 45 caliber cartridge that is too long for Blackhawks and is for the Red Hawks only Hence RHO
I shot it out of a 5 1/2 Redhawk and it is quire powerful. The pistol had a scope on it and I may not have needed to, but I sort of dodged that scope when the recoil brought up the gun so hard. I did not get to shoot any animal. I can only think of 2 critters that I would want to try it on and that is a 300-400LB Hog or a Bison.

PLease hang on to your 41 mag RedHawk. I have only seen one and it was a Blue Version, at a Pawn shop. It has some rust in the barrel and showed some wear. They were asking 600 for it and I did not want to pay that. I couldn't talk them down. It seems all pawn shops are using Gunbroker to determine their prices now.
