Can the .30-06 do more than the .270 Win?

    It is not time, it is desire. Or to put it a different way it is a causality chain.

    If the military had adopted the 270 and the 30-06 was delayed 10 years. We would be talking about how the 270 was the better more developed cartridge.

    As a general rule, I believe that the .30-06 is the more versatile of the two cartridges.

    The .270 is a good cartridge, but because the .30-06 can fire heavier, higher sectional density bullets than the .270 (200 gr and 220 gr bullets in the '06 have a higher SD than a .270 cal. 150 gr bullet) at 2400-2600 fps), I think the '06 is the "better" cartridge of the two.

    It really just comes down to what you're wanting to kill with it... Up to a certain body size it won't make a bit of difference, that's worth debating... In regard to bullet drop, it's not enough to make a flea's fart, especially if you're familiar with the ballistics.. We with some regularity kill 250lbs. hogs with .308s at 500+ yards and it doesn't shoot as flat or as hard as either of these two calibers mentioned, but it's irrelevant because we know where the bullet will be when it gets there..

    When we shoot those hogs with a 28" barreled .338 edge at that distance they most typically fall down and die... When we shoot hogs at that distance with a 22" .308 with handloaded berger bullets, they typically fall down and die... None of these hogs ever argued to each other who got hit harder..:cool:

    I have forgotten about the 7mm Rem Magnum round. It's .284 bullet really moves.

    I think the 30-06 is the most flexable round on the market today. Has been studied and used more then any other round, more options and availability then any other.
    For hunting or even combat its a all around great round.

    but once again you use what you like and what works for you.
    My hunting days ended decades ago, after the military I lost my love of hunting anything. Now I just shoot targets...usually with 5.56 and 762X39 and several handgun cals.

    This is a well-thought-out summary of the .30-'06.

    Is long enough to secure a 220-gr bullet, and the case capacity is big enough to drive the long bullet at 2300 FPS. This leaves the .270 Win way behind.

    Surprised no one has mentioned the history of the .270. IIRC, Wasn't it developed to get higher velocity & longer range by just necking down a .30-06 case? I think case volume behind the bullet is the same, is it not? So you can "reach out and touch" smaller targets at greater distance!

    I'm certainly not a ballistics authority, but I believe I read that somewhere BEFORE the Internet. (Sports Afield or the like)

    I have both and hunt with both. For someone of average skill who takes shots at average ranges, they both work just fine for me.

    You have to look at the marketing strategy to understand the .270, really, ballistically, it doesn't make a lot of sense. You do not gain effective "longer range" with a lower ballistic coefficient. You might gain a flatter trajectoy which translates to a slightly longer PBR but not as much as one would think. put a 130 gn bullet in a 30-06 and see what happens.

    The ability to hit targets at long range is much more in the hands of the shooter and their knowledge and skill than in a realtively few FPS. But shrewed marketers would have you think otherwise.

    At the time America was "30-06'ed" to the max. There was considerable interest still, in rounds like the .257 Roberts but Americans would not accept a "foriegn caliber" with things like "8mm, 7mm, 6.5mm" in the title or based on "Odd" bore diameters. "If we are going to have an odd caliber, it will be one our own making" was pretty much the sentiment.

    When it comes down to it, and with the benefits of todays projectiles, the wildcat "6.5-06" is a giant leap above the .270 in versatility. But in the day "All American" "with more velocity" is what sold new guns.

    They just hadn't adopted the term "magnum" yet...

    Imma do the .277 Nabuchadnezzar although the Methuselah sounds pretty potent.

    I started with a 30-06 because that's what my Dad had and I inherited all of his ammo, bullets, powder, etc. If I started from scratch, I'd probably go with the 280 Rem for deer and antelope, 338-06 for elk, bear, moose.

    As it stands, I have the 30-06 and 338-06. :cool:

    From Wiki

    "While it is true that a .270 Winchester case can be formed from a 30-06 Springfield case, the case length of a 30-06 is 2.494 inches (63.3 mm) while the case length of a .270 is 2.540 inches (64.5 mm), the same as a .30-03 Springfield. It is recommended that .270 Winchester brass be formed from .35 Whelen or .280 Remington cases.[11]"

    .270 - "Case capacity 67 gr H2O (4.355 cm³)"
    30-06 - "Case capacity 68 gr H2O (4.42 cm³)"

    So sounds like the extra length on the .270 is neck.

    A bigger diameter bullet gives more area for the burning powder to "push" against the bullet and more room in the bore to burn. For example a .338-06 can push a .338 220gr bullet with more "authority" than a 30-06 can push a .30 220gr bullet.

    This is an important, and often overlooked point.

    Reminds me of the story of a wildcat cartridge maker. He had come up the ultimate varmint cartridge. It was suppose to have an extremely flat trajectory and because of the speed it would not have to worry about wind drift as much.

    He had take a 50BMG cartridge and necked it down to .45. Then he took that cartridge and necked it down to .40. At this point he had to thin the neck because the brass was getting too thick. Then he took the case and necked it down to .308. Then he necked it down to .264. Again he had to thin the neck. He was finally able to neck it down to .224.

    He then put a gun together with with a barrel chambered in his special round.

    His test loads were with with the same powder as normally loaded in a 50BMG.

    He said that he was only having one issue with the ultimate varmint cartridge. It was vaporizing the bullet before it reached the end of the barrel.
