I have a Linebaugh .454 conversion Ruger Bisley 4 5/8th that I can barely hang onto with full loads.I'll save it for Alaska bear country.I regularly carry a 4" 629 .44 mag.
Well why did the silhoulette shooters choose to use the .44s over the .357s in their sport?And it has been proven, from time to time, that the .357 can do everything a .44 magnum can do.
Just took delivery on mine...believe I'll start out somewhat short of 575 gr, though!! Is there still room for powder??
Whoa Whoa Whoa. Where did you get the 575g loads for the 460. the biggest i've been pushing is the 395g GC from cast performace.
What is the difference in power between a 44 mag and a 454?
The 454 (No Decimal!) in a true .4515
IMO the best way to measure the overall power of a cartridge is the energy the projectile delivers to the target.What is the difference in power between a 44 mag and a 454? There is a discussion among friends. One saying the 454 is around 1.5 times as powerful and the other saying the 454 is 2 times as powerful as the 44 mag.
What is the best overall measure to determine the power of a specific cartridge?
Glad .38 Special and Redhawk1 jumped all over that!! And lets all remember, though a S&W .460 is indeed a hand cannon, it only approaches what a .308 rifle round will do...not serious big bear medicine in my mind (but better than nothing in an emergency!)
Nope
The regular commercial rounds for the .460 tops at 2300 ft/lb, a .308 is at about 2700-2800 average...not quite the same power class..
Yes there are particularly hot .460 rounds out there from small manufacturers that can go over that figure, but you can hot rod a .308 too you know....
If you add the fact that a .308 rifle bullet has much better aerodynamics, BC and sectional density, at 100 yards a.460 pistol round will lose in proportion much more energy compared to the .308
After all you do not shoot your game at the muzzle...
P.S.
You cannot extrapolate the power differences between two rounds comparing the pressure values....there is not linear relationship between them
.4510= .451, then it goes up from there to the .4515, to .4519, then it is .4520=.452
There is more to take into consideration than just speed. Bullet weight is also a factor.
Go to a ballistic chart and plug in the numbers, you will be surprised at how close a 308 and a S&W 460 Mag are. Now use the same bullet weight.
A S&W 460 Mag with a 200 gr. bullet is go 2300 fps, and a 308 with a 200 gr. bullet may reach 2350 to 2400 fps, not much of a difference there.
