A few threads in the past and present have sparked me to start this debate thread because of a growing and devoloping theory I've had for years and years now.
Now, I don't want this to turn into a BS or ******* match, I want us to be able to discuss these things like the grown intelligent and intellectual adults we are. We should be able to do that.....I hope.
When talking with many hunters over the years about different calibers, I have heard many and numerous storys of smaller calibers being shot at great distances successfully, but you don't seem to hear about them on here.
This next paragraph is just using the 7mm as an example....As I am a .284 nut, I have quite an intimate knowledge of the 7mm's, which is why I used it as compared to other calibers, also the fact that the heavy 7mm's can carry BC's that are VERY close to (and in some cases higher) than the larger diameter calibers. Also, since we had the 7mm vs .338 conversation a few weeks ago, I decided this would be a much more interesting and friendly way to have this discussion.
Here is some opinion and a little controversy from my thoughts...
I have faith that a really heavy, high-BC bullet (ex: a 180 VLD or 190 Matrix) from a big 7mm (.284), such as a 7mmSTW, 7 RUM or 7mm Allen Magnum, could be effective out beyond 1000-1500 yards, although I have no personal experience killing anything that far. I have heard about and seen videos and pictures of real people and true stories, killing very large game at great distances with a 7mm RemMag on the interwebz....And Carlos Hathcock made numerous 1,000+ yard kills with a .30-06 Sprg MIA and some very impressive shots with a Rem 40X .308 Win, with a crappy scope, and primative technology (as compared to today). So my brain begs to know why do we actually "need" these enormous calibers with all the weapons and bullet technology we have today. If people could successfully do it without them back then, why do we "need" them now? I understand everything has its limitations.....Which is what separates a .22LR from a .338 RUM. So as far as velocity and energy, bullet weight, etc....I understand all that.
Now, just so you know, I am NOT
putting down anyone's choice of caliber. "You brought it home...You feed it." That's what my dad used to always say when I was growing up.
Everyone has a preference and a choice. I just want to know WHY you bought what you did, and WHY you felt it was the only option for your task at hand, forsaking all other calibers out there?
I have a theory, but yall will probably think I'm nuts....I just want opinions rather than a bunch of heated BS. I want opinions as to why, if you think my theory is correct, or incorrect, not a bunch of "because it just does...." type of answers. I also don't want a bunch of negatory answers, I want factual evidence as to why my theory would be correct or incorrect. I have been gathering this theory for a while. I don't want a bunch of charts that have been manipulated and spun to work in favor of your choice, etc....I want to see hard factual evidence of what makes the monster bores better than standard large magnum calibers at long range.
Here's my theory...
I think the larger bores with the heavier bullets might carry the energy farther out, but they also move slightly slower from the get-go, and with a much larger overall mass and more bulbous shape, would lose velocity a great deal faster, which is why you need so much powder and a such a large case capacity for them to be efficient at such long ranges......
Wouldn't a faster moving bullet that weighs less, and has a more aerodynamic profile, follow a better trajectory to the same target at the same distance, which in turn, even though it is a lighter bullet, will expel the same amount of energy, based on the higher velocity it maintains as it reaches the intended target, as compared to a larger, slower moving projectile with a rapidly decreasing velocity?
These are just thoughts I have, and I would love to hear everyone's opinion on them.
