Thirty years ago, a friend stopped by to try out his .458 Lott double rifle. Originally a .458 Winchester, he figured he'd need the add'l smack that a .458 Lott would provide on his upcoming African adventure. He showed up with the gun, a ten pounder on the bathroom scales, and a fist full of cartridges. After a couple of rounds of pasture clay bird shooting, we decided to try the new cannon against a standing, but dead, white oak tree along one of my lower pastures here on the farm.
With my two teen aged sons and another friend from work that'd played defensive football for the Cowboys back in the late 60's, we watched him load up both barrels and 'stalk' to within 50 yds of the oak. Thumbing back BOTH hammers, he touched her off at the offending tree and was promptly knocked off his feet by the recoil.
The gun had double triggers and he'd pulled the forward one, and managed to pull the rear as well during the heroic recoil. Dazed & dusting himself off while getting up, he offered us the chance to give it a try....gotta remember that big, ex-Dallas Cowboy football player's response, "not on your life"...and we retired to the porch for some Kentucky "Fruit Juice".
He was successful on his African hunt, bagging a big Cape Buffalo with the gun, but I doubt the gun's was ever fired after he returned. A single .458 Lott cartridge produces 75 ft/lbs of recoil in that weight of gun, and he'd touched off two of them. I've often wondered why he didn't dislocate his shoulder. Penetration by those ~500 grain solids was impressive, I'm sure, but they didn't punch through the 26" diameter oak.
Best Regards, Rod
