I have owned a LSI/Rossi chambered in 454 Casull for some time now. The recoil with full power loads can be compared to the 444's and the med/hot loaded 45-70's(which I own both). My weapon has the 16" bbl and the weight is <6lbs. This makes the felt/precieved recoil pretty stiff. The muzzle rise is more than my 444 and 45-70 although they are both carbines as well.
BUT.....the weapons cannot be compared simply because the 454 is a "pistol" round. Being short, the action can be cycled faster and the mag can hold more ammo. Not wanting to start a "battle" with the "self defense against the larger bear" people around here,but I would much rather have my Casull strapped to my back with it's 8+1,than either of my other carbines mentioned above. It will simply deliver more FPE than either of the other two.
'Nuther but......I also would love to see either Marlin or Winchester(I personally would pick Marlin)come out with a "92 designed in 454,and 460 and 500 S&W Mag. If the beefier weapon would weigh in at 7 lbs that would be even better as far as somewhat dampening the effects of recoil.
Now lets see.......a Marlin with fair looking wood for $750 or the others for $1800 ?? I know which one I would pick. -----pruhdlr
