What the guys told you about the PRB is correct. I think the important thing is field experience on how the PRB preforms. I might add that even with modern ballistics there remains today arguments as to the old cartridges like the 45/70. The slower, heavy bullet doesn't compare to the high velocity, light weight bullet and yet it does the job.
What a hunter needs to know is what his round is capable of doing-notice folks are telling you "two broken ribs" that spells "broadside shot" at 60 to say 100- maybe a bit farther yards-not a shot in the rear haunches that is expected to plow through the innards up into the lungs.
