Home Forums Hunting & Shooting Express Rifles and Big Bores Only The great 458 Winchester. Everyone should own one at least once

Here is that 500-gr/.458 CEB used in your 460 G&A:



The 500-gr HYDRO without feed cap is 1.525" long, with feed cap about 1.680", too long for my .458 preferences.

At the CEB site here is a 570-gr/.510 brass FN recovered from "elephant shoulder":



I am guessing it came from a .500 NE and probably had MV no more than 2200 fps and would lose about 100 fps for each 25 yards initially.
570-gr/.510 sectional density = 0.313 with greater meplat diameter
500-gr/.458 SD = 0.341 with smaller meplat, for greater "Penetration Index" at similar velocity.
No wonder the .510 was recovered and the .458 was not,
if we consider similar resistance from a .510 shoulder shot and your .458 head shot ...
But if your bullet was impacting at higher velocity it had to overcome a higher initial resistance from the impact media ...
Which it did.
