Nah, that would make the whole thing too complicated for folks.
God bless ya Jeepy, boy it didn't take long....
"....No its not all about what you have, its how you use it...."
Using that simplistic approach, a 22LR would become a legitimate elk hunting round (in the right hands --- oh boy here we go) --- nope, IMO a meaningful dialogue requires a leeetle more qualification, thought process, and articulation.
BTW, I certainly do agree with you on liking some of the older cartridges especially about the time they turned "modern" around the start of the 20th century! (Must of been a lot of howling and whining and carrying on by the black powder boys back then as similar to what we see today). Anyway in line with your train of thought on the matter, I kinda agree as I believe the '06, the 375H&H, and the 416 Rigby will turn 100 years old WELL BEFORE the 270! The 45-70 is already about a 125 years old or so. Not that it really means diddly squat as long as they are comparitively competent cartridges, but it is a nice circumstance. Thanks for the idea, but IMHO it doesn't take away from the mid to late 20th century magnums at all.
