...that load is good for 1500 ft.lbs of ME.
That's painful in some rifles; in a revolver...well, what the heck. Don't shoot it anymore than you want.
BTW, if you venture north, we can borrow a .500 Linebaugh from my favorite gunsmith and check out the recoil at the nearest outdoor range.
For some reason, nobody with an indoor range wants us shooting that custom Ruger. Can't imagine why...
...probably has something to do with not being able to offer range ammo in that caliber.
