You cannot create nor destroy energy but the six pound weight of the revolver may tame some of it. Marketing hype will make up for any difference.It seems that S&W has taken the beasty 50 cal. frame and developed a cartridge for it that "leaves every other big bore hunting cartridge in the dust" - with recoil supposedly no more than a mid-size .44 Mag. The new revolver weighs 72 ounces and will also shoot 45 Colt and .454 Casull.
There is no such thing as a free lunch and a potent round will exhibit all of the characteristics of a potent round. Recoil is no exception.
For those of you that believe S&W's sales pitch, contact me now! I have decided to put the Queen Isabella Causeway on the market and must sell now! My loss is your gain. Cash sales only!
By the way, my 3 1/2 pound lightweight Super Redhawk puts out 300 grain loads at over 1600 fps and that is only because I felt the load was sufficient for my use. Let my know how you feel after packing your five pound S&W around all day.
