"let time and success decide which will be popular or still with us in the future"
Sure, all handgun ammo has it's place and it's purpose, it's followers.
IMHO the .454 Casull and his 50 years+ is STILL a marvelous round, packing quit big power in a small package and more specifically because it's hosted by an even more marvelous quality handgun, the F.A. Model 83. I can't deny that, but i'm no great writer, nor Clint Eastwood to change opinions...
You know, i cannot blame M.Cooper for his "WHOW" at first glance and his sober "unpractical" afterwards.
Didn't we do that with our first love :-) ouch!
i'm kidding...
