Makes me wonder what the 460 is capable with custom loading.. |
The handloaded .460 isn't much different than factory offerings because factory .460 ammo is already loaded to an OAL that almost fills the cylinder. Factory .500 ammo is not, with the exception of some types of ammo produced by small companies like Ballistic Supply.
The .500 has more case capacity and a bigger bore than the .460, and it operates at almost exactly the same pressure. That means it can do things the .460 can't IF YOU WANT IT TO, such as delivering 35%-40% more muzzle energy than the .460.
