I have always been skeptical about claims that Kinetic Energy somehow equates to stopping power. Shill gunwriters love the KE formula (KE = Mass X Velocity X Velocity) because increasing velocity by 10 fps increases KE by 100. So it makes it easier to shill for higher velocity products, just a little increase in velocity and the number goes up by a huge margin. So it must be that much better! Shill, shill, shill.
What I recall, from physics, is that momentum is the only energy conserved in collisions. That is Momentum Energy = Mass X velocity.
What the 327 guys did was increase velocity to the point that the KE was equal to a 357 round, and claim that their little round is just as good.
I think history is replete will all sorts of similar high velocity high jinks that were not as good as the marketing.
The debate is never whether bigger is not better, the debate is whether smaller is as good as bigger.
Go with Big. It is the sure thing.
The 32's have all died a slow death this one probably will too.
Shot my 32 S&W Long at the pistol range yesterday. It is so underpowered that when a large lunged individual on the left was talking, I could not hear the bullet impact on my gongs.
However, when I switched to my 357, no matter how loud that guy talked, I heard the ping.
