In any caliber, the heavier bullet will ALWAYS be better <span style="font-style: italic"><span style="text-decoration: underline">at distance</span></span> than a lighter one. It's simple physics. </div></div>
WRONG, Really Wrong, when you say "simple physics", do you mean simple minded physics? Have you ever heard of BC? Let's us examine this a little bit further: Using the Sierra ed 5 manual, the 170 gr 308, stock #2010 has a BC of .205@ 2400fps and above, .248 between 1800 and 2400fps, and .293 @1800fps and below. Now let us compare with a lighter 308- let's say the 168gr SMK, stock #1930, BC .488 @2800fps and above, .494 between 2000 and 2400fps, .484 @ 2000 and below. This is just one of the thousands of examples that could blow the heavier bullet-simple physics nonsense out of the water-may I suggest you read anything to do with Ballistic Coefficients-even 5 minutes would help.</div></div>
I'm going to point out a few things here.
First, this is an example of why many people with experience don't respond often to serious inquiries. You take a simple answer to a simple question and some retard has to come along and point out a completely irrelevant example to the question at hand. Your response Paw Print, is why Lowlight authored the quote in my signature.
Let me define a little thing called "context". The "Context" of the conversation where we were discussing two bullet weights of the same type, not an entirely different bullet type. So your fallacious example of comparing a .30-.30 hunting bullet to a match king shows that you don't know what the heck you are talking about. Stop parroting what you've read and try to learn something.
Two different bullet weights of the same caliber and the same TYPE means that the heavier bullet will always win out.
Now since the armchair lawyers want to ensure that all the posts have "fine print" indicating what common sense should already make clear I'll say what shouldn't need to be said. First, same caliber, same chamber, same bullet, different weights. Second, only safe and realistic loads need apply. So if your claim that a certain chambering wont safely and accurately fire a bullet, then that parameter is not included. I.e., if your 308 cannot stabilize a 240smk, we shouldn't have to say "except the 240smk", that should be a given.
My only qualifier was "at distance", which again I didn't think needed explaining but I guess armchair quarterbacks cannot define what "at distance" means. It means at the longer distances where the bullet remains supersonic. So if we're talking a 308, longer distances would mean 700+ yards. No one would argue that a heavier bullet in the 308, or any caliber (of the same type, i.e. Matchkings) will not do better. That is why the 175 does better than the 168 and even the 155 AT DISTANCE.
Now what defines "better"? Again, here is an example of where common sense shouldn't need to be explained.
Wind and gravity are the factors that shooters cannot control. And gravity is a constant so that is nullified. Shooters can control load consistency and shooting technique, however all of the attention to detail and perfect technique cannot control how the wind blows, swirls, or otherwise affects the bullet. In a vacuum it wouldn't matter about how flat a bullet flies as the only affect would be gravity therefore the arch of the bullet would be the only concern. So my 308 and your 338 will be inherently just as accurate as long as the load is consistent.
Now when we bring wind into play the flight time and BC affects how the wind will influence a bullet on its way to the target. A "better" bullet would be the one with the higher BC, which in turn would prevent the wind's influence better than a bullet with a lower BC. Less wind drift means a more accurate and consistent shot all other factors being equal.
Now there is the argument that flat and fast can outperform slow and high BC and I don't believe this is the place to discuss that however, the point is that "better" can be defined in the context of this discuss as a chambering and components that keep the affects of wind to a minimum. Therefore a bullet that allows for .75 mils of drift @ 10mph FV is going to be better than one that calls for 1.5 mils of drift @ 10mph FV.
Now Paw Print, while you're in your time out for calling me an idiot, I suggest you read much more. Whether it's here, or another site where you were ran off, learn before you go running your mouth. Or better yet, go out and shoot. Let the men with experience talk. If we want page turners, we will give you a call.
