Perfect caliber for "Tactical" rifle?

My Sincerest Appoligy to the Forum, I did meant you are all wrong I and have it come out the way it did. Now that I re read it I can see that it does look real good. Please forgive my stupidity and my use of wording.

Hey, Karsten, stuff just comes out all wonky, sometimes. That's why we keep yelling "Think twice, post once."

With no facial expressions or body language to help figure out what folks actually mean, when posting these comments, we all gotta be more careful. That's why I use smileys fairly often. :)

Slightly OT question

Bogie -- You brought up a topic I've been meaning to post for a while... you say you'd prefer a ".308, with a fast twist, built to shoot 240 grain matchkings..." Can you really load a 240 gr MK into a .308 case? I'm not so concerned about having a tight enough twist (for example, the Savage 110 "Tactical" has a 1 in 9 which should be fine to stabilize this), but would you be able to get a big enough powder charge in there without excessively compressing it or exceeding max OAL?

I'm a firm believer that at long range, you want a heavy bullet. Light and fast is great - and maybe preferable - at close range, but my understanding of Physics is that a little tiny pill sheds that higher velocity much faster than a big old monster, so the heavier bullet is actually travelling fadster than the lighter one by the time you get way out there. Sure you can hit things at 1000 yards with a 50 grain .223, but you're just barely penetrating cardboard at that range, while a 405 grain .45-70 is still smashing through several inches of oak. Wasn't it American Rifleman that carried an article on the US Army tests of the .45-70 at ultra long range about a year ago?

Note: I'm not saying that a Trapdoor Springfield in .45-70 is the ideal tactical rifle.
 
Bruegger: Generally, heavier bullets = longer bullets = better sectional density and ballistic coefficient. Spitzer boat-tails have the best BC, and thus retain their velocity better.

Many loading-data handbooks have excellent explanatory material about the various bullet designs and exterior ballistics. IMO, the Sierra book has the most amount of information about "why"...

Speaking of ideal rounds- read a "Special Weapons" article yesterday about just this. It seems that a 6mm, 100 grain bullet @ 3000 fps will have identical flight characteristics to a 190-grn .300 Win Mag...and the article suggested just that, a round he wanted to name the "6mm Optimum". :D Guess I'm not the only one who's thought this!
 
Which was precisely the reason I chose to drove a .264" 140gr MtchKing over 3000 fps for 1000 yard work. Funny how there's more than one way to skin a cat, ain't it?
