Very interesting.
I love the way it appears that when the temporary cavity collapses, the unburned gasses reignite, and then expel the gas back out of the front face of the gel.
I've yet to see studies which come anywhere near being inclusive enough to draw meaningful conclusions. There are far too many variables in real world situations to declare any handgun caliber superior to another. The "data" available when .38 & .357 were the predominant calibers in LE is far from complete.
Shot placement is everything with any handgun caliber. Rifles are superior all the way around.
I have no doubt about the usefulness of the 44 mag as a hunting cartridge, it is easily capable of killing large mammals. The difference is that hunting and defensive handgun use have very little in common and there is a price to be paid when trying to hit a moving target with a handgun under the type of stress a life threatening situation brings. No amount of energy or bullet diameter in a handgun cartridge will make up for the inevitably large percentage of less than ideal hits which come with defensive pistol use.
That is excellent. I love my 29-2! Some nice 240gr round moving out ~1300 fps...you can feel the energy for sure!
Like hoosierdaddy1976, I hit replay several times.
BTW, some of the comments in the reddit are hilarious. Thank you for sharing that link.
