My experience has been the exact opposite as yours
@HookMeUpII ...
A 300 gr 44 Mag shot from a carbine is traveling about 1625 FPS.. roughly 25% faster than it would be from a 6" revolver (roughly 1300 fps)..
That is WELL below most centerfire rifle velocities (62gr 223 @ 3100 fps for example)..
As a result, far more often than not, big, slow moving projectiles tend to cut holes that are roughly the same size going in and going out.. there is relatively little to no expansion (nor is there a lot needed in most situations)..
Whereas faster moving smaller projectiles tend to rapidly expand (especially true in many small bore calibers since most of the ammunition designed for those calibers is specifically designed to expand quickly or even intentionally fragment upon contact)... and are known to create considerable pelt damage..
You get very similar results with a 45-70 shooting "trapdoor" loads.. where a 45 caliber, 300 gr projectile gets pushed about 1550 FPS out of a rifle... I've probably popped a dozen pigs with 45-70 trapdoor loads.. using broadside shots the exit wounds are negligibly larger than the entrance wounds..
There is a reason LOTS of people (experienced hunters and PH's alike) recommend 375 H&H with solids for the tiny ten.. you get the same hole coming out as you got going in..
If expansion is a concern with a 44 mag or a 357 mag out of a carbine (I wouldnt think it would be.. but.. if it is for some odd reason).. simply load up FMJ ammo... and youre going to have roughly the same sized hole on both sides (not nearly enough speed/energy.. or enough bone or body mass to deform those big, slow moving projectiles)..
