I lived in MM for 58 years and every elk hunter I ever met used either a 30-06 or 7mm mag except for one friend that uses a .338.....never heard of using anything smaller.....

Actually, the 280 has identical muzzle energy as the 270 except it drops 2 more inches at 500 yards. This is according to Hornady using the latest SST Superformance loads.

This is very revealing and a bit of a reality check.
Check out this monster moose being dumped by a 30-30. Go to 24:50 for the shot. http://www.youtube.com/watch?v=6xZsg...UHderIK7Ng0BZQ

Generally, with the 06' cases the larger the diameter bullet the neck is sized for, the more potential ME you are capable of safely achieving, up to about .35caliber, where it begins to fall off in potential. The sweet spot for the 06' case seems to be between .277 and .338 for the most efficient loads. Even so, hand loaded, the .270 versus the .280, the differences in ME is fairly negligible, we're only talking maybe 100ft/lbs difference, if that. No game, or piece of paper you're shooting at is going to know the difference between the two. Last edited by JD0x0; September 30, 2013 at 02:09 PM. |

.270WIN vs. .280 Remington
While I have, and love the .270WIN, the .280 has a slightly higher SAAMI presure limit (mostly in deference to the many really old guns out there chambered for it), and bullet selection is greater.
It's not enough of an advantage for me to run out and get a .280, though ...... I've got a .270WIN and a load for it that works pretty well. |

The sources I found list the .270 Winchester at 65,000PSI and the .280 Rem is listed as 60,000 psi max. http://en.wikipedia.org/wiki/.280_Remington http://www.lasc.us/SAAMIMaxPressure.htm I believe this pressure was for the early made .280rem's with weaker chambers, and it's plausible to safely load .280rem up to 65,000psi like the other 06' based cartridges, even though the SAAMI max for the .30-06 is listed at 60,200psi. I believe newer actions can safely be loaded to 65,000PSI as well. |

There are too many variables when throwing hand loads into the mix. How can hand loads be objectively proved? I picked the latest greatest high performance Superformance loads that are the fastest in the industry at the present time. Hornady is not sandbagging the 280 Superformance load over the 270. To suggest there is some magic variable in hand loading that can bring more out in one caliber and not another is absurd.

Your just looking at paper ballistics put out by a manufacturer, which might be totally different from the real world ballistics from your rifle. They only way is for each shooter to get an objective opinion of any load is to shoot it through their own rifle. You might find what Hornady puts on paper might be far different from what you get in real conditions. Plus without shooting any of these loads across a chronograph you'll never really know how they are performing. That is the only way for me to actually prove that my ammunition I load is doing what I say it does. That way I know that my loads are close to the published reloading data I use. You should really take what the manufacturer published data with a grain of salt. Even if you shoot factory loads if you really want to know what they are doing spend a little money on a chronograph and tripod. Go to the range and shoot a 10 shot string across the chrony and then you'll actually have an idea of what the cartridge is doing. Quote:
At 65K psi the .280 would be nipping on the heels of the 7mm RM and possibly beating it with certain weight bullets. Remington already had a successful thing going with the Rem Mag, but they had downloaded the cartridge to where it only slightly out performed the .270. This was probably done to make the recoil from such a small bullet more tolerable IMO. There is no real difference between the .270 and .280 except on paper. In modern bolt action rifles they are ballistic twins when loaded with equal weight bullets at equal pressures. Both are great cartridges in their own right.

A test barrel keeps a level playing field for a even comparison. All I can tell you that independent tests on YouTube confirms their speed. I can see a difference between normal SST and Superrgormance SST out at 300 yards. Not much, but it would make a bigger difference at 400-500 yards. In my gun 130 SST Superormance are tack drivers. I sight my gun in to be good for 0-300 yards without hold over.
..I would be lucky to reload this accurate for my JOC rifle. 3 shot 100 yard group. I am going to chronograph them this week for a free custom turret for my Leupold VX6.

Nice group, but I'll stick to reloading as I can do the same thing cheaper in the long run.

If you're a .280 Remington aficionado, odds are you eventually get .280 ai. Nosler makes brass and ammunition for this round (Nosler actually SAAMI standardized the round) , and heck, Kimber chambers rifles in this caliber. With a .280 ai you get close to 7mm Remington Magnum performance with less recoil.

Plus if you load a .280 in a modern bolt action to 62-65K psi you won't see an appreciable difference between it and the AI version as far as speed goes. The AI isn't anything magical or wondrous about the 40 degree shoulder. Larger powder charges with smaller cases produce more pressure that creates velocity an recoil simple as that.

A quick look at my Nolser fifth ed. shows about 5 to 10 grains more powder for the 7Mag than the .280AI, with modest (50 to 150 f/sec) gains in velocity ...... 10-15% more powder for less than 5% (in most cases, 2-3%) increased velocity. On the bright side, .280 don't have the stupid belt the 7 Mag does ..... and brass can be formed cheaply. |

You have to compare rifles of equal weight. You're comparing apples to oranges. What is the kick if you had a custom Kimber Mountain Ascent chambered in 7mm Remington Magnum, more than 26.91 ft/lbs of recoil from the .280 AI I would guess. What is the kick if you had a rifle weighing 7.0 lbs for the 7mm Remington Magnum and the .280 AI?

Choosing best all around caliber?
I think I've decided the .270 is the best for me. It's mainly going to be used for target, coyote & deer in that order. Anything bigger or tougher like black bear or feral hogs could possibly be doable with specialized hi performance rounds. . I would like to have a nikon zoom scope with illuminated cross hairs. I have some larger & smaller cal. rifles so the .270 seems to be the best all around- middle of the road choice for me. Ammo shouldn't be hard to find either.

You don't need "specialized rounds" to use a .270 on black bear and certainly not feral hogs.

I hate to derail the thread and get it back on topic. The OP has chosen a 25-06 and its a good choice. But a 257 roberts might have been better. It should have a longer barrel life and if reloading use a little less powder and most of all be better for elk or bear if he gets a chance at those. Better than a 243 I would think.
But if it were me I would get a 7-08 in a slightly heavier gun than my remington model 7 with the 18.5" barrel. A winchester model 70 featherweight might be my first choice. But any 22" barreled 7-08 should be a light recoiling gun. And better than a 243 for almost all hunting. |

Didn't he say he decided on the .270 just 2 posts up?
