It's an interesting article. Takes a lot of time to read and digest. I spent a while on it last time, got to the beginning of Section V and had to go to bed. I certainly agree that none of the previous "stopping power formulae" have any validity, but I doubt that he's going to come up with anything better after all this verbiage.

After reading and skimming this whole thing it pretty much boils down to shot placement over power. Nothing new just better proof that there is no formula to predict bullet performance A bad day at the range is better than a good day at work. | |||

Right about shot placement. It is nice to see emphasis on what happens when the BULLET hits the target, instead of what cartridge it is fired from. I think many times the industry pushes Cartridge performance w/o realistic considerations for how that affects ones ability to HIT where they want. Flat trajectory helps but flinching does not. | |||

He points to a lot of data showing that bullets' terminal performance is often better at LOWER impact velocities, and even suggests that with some of the magnums the shooter may be advised to designate a "do not engage zone" from the muzzle out to some range where the bullet's velocity drops to an effective level. Interesting idea. Not one that many present pushers of magnumized rifles would support. "A cheerful heart is good medicine." | |||

For those of you with a life, I plucked some interesting data from the report. 444 Marlin sure looks good here!!
