Well, I finally sat down and studies ballistics on the .270, .280 and .30-06.

Suprise, suprise - not a spits worth of difference on these highly regarded and highly discussed cartridges when talking 130 to 150 gr in the .270, 140 to 160 gr in the .280, and 150-165gr in the .30-06.

Am I missing anything? I looked at energy and drop at 200 yds and 300 yds sighted in at zero of 200yds. Everything is within 200 ft-lbs and about 1" of drop.

I looked at the charts on Federal's website and on Conley Precision Ammo website.

Have I missed anything? Are they all the same thing, basically? Yes, I know that you can to 175 gr in the .280 and to 220 gr. in the .30-06, but for plains game, deer, antelope, elk - they all do the same thing and hit with the same "wump".

Comments????

WHY would you be surprised at your findings? They are all derrivatives of the '06 case, have basically the same internal case capacity. The only difference between the three is .031" bullet diameter.

What did you expect to find? Fountain of youth?

You got it, and to make it even less impressive than it is now, add in the short rounds like the .308WIN and 7-08. All are about the same with mid weight bullets till the metal hits the meat. Then some make bigger holes and some penetrate better.

After you play with those #'s, compare these rounds to the magnums in the same caliber on a point blank range calculator and you'll see for all that extra recoil and gun powder you burn and suffer, they're good for about 30yds extra before you have to hold over just like the non-magnums. fun stuff.

I've had better luck w/ one shot drops w/ a 30-06 vs a 270. Also the deer seem to travel further when shot w/ the 270 for me. Same type of bullets and similar speeds but, just have better luck w/ the 06' I guess. Maybe just me.

For a general purpose rifle get a 30-06, use 180 grain bullets and sight in for a 250 yard zero and there's nothing you won't be able to hunt on this side of the Atlantic.

Thanks for the comments on this.

I am an engineer and tend to over-analyze things. I have shot all three - have fallen for each on several occasions and own all three.

Then I woke up and realized that all that each of you have said is 100% true.

To answer onefunzr2 - yes, I would like to find the fountain of youth, but the reality is that it is much like Dorothy in OZ - There is no place quite like home. In other words - each will work, be happy with what you have and shoot well.

I just like a good story, a good romance with a rifle - and the .30-06 has a huge following, but no romance. It is like the homely girl at the prom - everyone is her friend but not her lover. The .270 has a following, the .280 has it's cult but the 30-06 has admirers but no passionate lovers.

The more I looked into the ballistics of the .30-06, the better I like this "homely girl". It seems to shoot a lot of different bullets fairly well - so this homely girl may have more to her than I thought.

Thanks for the help.

Then let me be the first LOVER of the classic and historic 30-06 to speak to this. I got my Mod.70 in 1964 and have carried it all over the US. IMHO it is THE one gun for all game in North America except the big bears and the 220gr should do them. I have shot deer, P dogs, Song dogs, etc and they all died. I know a PH in Africa who owns 2 rifles, 375H&H and 30-06.
It is good on plains game as well and has taken them all.

I'm with you there. The 30-06 didn't really float my boat until mine started liking the 200 gr Accubond at 2700 fps. That carries a more energy and is more suitable for big game than the 270 or 280 can manage IMO. The 270 has it's place with 130 gr Triple Shocks for Antelope.

The real difference in ballistics comes with the 300 win mag. The 7 mag starts to hop-skip-...... but doesn't quite jump up like the 300 win mag does.

Really all you need is a 22-250, 270 and 338 win mag. Each one of those is signifacantly more than the last.

Woods-I would bet that comment generates more than a few replies - both in agreement and disagreement. I have a .22-250, a .25-06, and a 7mm Rem Mag. Have never, and likely will never hunt anything larger than feral hogs and south Texas whitetails, and have plenty of gun for both. But, I still am about ready to build a 6mm Rem and I would like to have a .35 Whelen.

Well now, to me this is what makes this fun.
I would say a 22-250, 30-06, and 375 H&H is all you need and there is a good spread as well 40gr to 300gr. I just happen to want the 458 Lott fer fun.
Ain't it nice someone makes them all or we would
have alot less to talk about.

You guys are singing my song. I like variety in wine and jobs (not women, one is plenty, not cars - too expensive). I have been through several rifles, makes and models. I have settled on the Model 70. I have several calibers and have decided to get more proficient in a "big one" and a "little one". I like the .375 H&H and am trying to settle on the little one. The 30-06 has caught my eye - efficient, no frills but dependable.

I like all of the caliber choices but it makes me want too many and not settle on one or two.

Variety is was makes the marketers happy.

There is no substitute for shot placement in big game hunting. I think that's why the 06 shines. Same for the 270 and 280.

Three rounds to cover it: Hummm, how about 223, 270 and 9.3 X 62 or 243, 06 and a 375 H&H or just for larger game a 270, 9.3x62 and a 458.

Yup...the only bad part about the .30-06 is that after you have one, it's hard to justify other guns in the near vicinity.....it covers the distance from the .022-250 all the way to the .375 H&H....and with ease I might add.

It is no different from my Tahoe. I had to pick between a dozen variations with minor differences but they all do the same thing.

You could also include in your list the 30-06 on steriods: 9.3x62!

This cartridge will push a 250BT at 2600fps and produce 3780ftlbs at the muzzle. It will produce more energy at 100yds than a 30-06 w/ 180gr bulet did at the muzzle at 2750fps. And what do you give up? Two inches of drop compared to the 30-06 and three compared to the 270 w/ 150gr@2825fps. I have a 270 and several 30-06s, but the 9.3 is a beautifully balanced cartridge at home any where in the world. (Drop measured from the bore.) Kudude
