If velocity is not a factor then why is the .357 Mag. better than the .38 Spcl.? Would you rather be shot with a 40 gr. bullet from a .220 Swift or a .22 LR? Of course velocity can be a very relevant factor. ISP found that out in the 80's with BPLE and the Win. Ranger 115 gr. +p+. Nonetheless, every generation has to "reinvent" the wheel.

Remember first & foremost that an ammo company's No. 1 goal is to sell as much ammo as possible. Everything else is secondary. I still shave with one double edge blade razor as disposables with two, three, four & even five blades don't shave any better & usually worse, despite what Gillette tells you.
