The worst I have fired is a 4 inch 500 S&W magnum with 700 grain Underwood ammo.Brutal is an understatement!
I believe there is the possibility of a Handbone crunching load with the X frames.

Or just ripping your thumb off.



While handloaders can achieve serious recoil in most any handgun, the biggest smiles/laughter has been introducing shooters to the M460 3.5".
As they shoot the increasing charge weights a sudden seriousness to the power in their hands is appreciated.
Never had anyone eagerly ask for another max but safe load.

Stay safe
Have fun.
