Home Forums Reloading Big Game Rifles .270 win vs .280 rem

This whole discussion is insane, BUT it's lasted for how many pages? JB's "only rational argument" was within the context of trying to find any REAL difference between the two cartridges. Ammo availability is a REAL difference. Whether YOU would loose your ammo or not isn't the point.

Stupid people annoy me.....

NO, what's insane is some damned hight and mighty GW coming in here and pouring water on a perfectly good fire, by using logic to difuse an damn good argument fueled by gun loonies debating the finite differences in 2 cartridges whoes only real difference is the .007" difference in bore diameter! Damn JB....DAMN him!

Thanks, John! I feel better now.........

Case Closed.

We are not really having this discussion, are we? Please tell me no.

I think it's time to move on to ".243 Win vs. 6mm Rem."

Reloder 28,

I believe he brought 3 boxes of .280 ammo. Some was used up when a scope went crooked (I believe one of his daughters fell on it), some was used up chooting at coyotes, and some was used up when his wife shot quite a few at a distant "wounded pronghorn" that turned out to be a white rock.

The word you really needed was "sown," not sewn. Sewn means needle and thread. Illiterate people offend me, especially those who have apparently never made a mistake in their life, or experienced enough of it to realize s--t happens.

280 has th e velocity advantage, 270 has the b.c. advantage. neither by much.

I shoot 270's cause they work, can be found everywhere, and I suppose it is the only link between me and normalcy.....if that is a word.

I have only seen a guy forget his ammo one time on a bear hunt. It was a .300 RUM and none was to be found anywhere. Funny thing is the guy had cases, dies, powder, primers, and bullets in a box in the back of his truck and the outfitter had a press. He was reloading some extra ammo "just in case" over at a buddies house before the trip and never took the stuff out before leaving.

I have seen several instances of what MD described. Guys bring a box or 2 of ammo and it gets shot up somehow. Usually a sighting problem of some sort.

The 7mm bullets have a significant advantage in the BC department... it's the velocity advantage that's really moot. ~JT

How so? For a bullet of the same weight the .270 in all, but a couple of cases will have a higher BC. If it doesn't, it's the bullet designer who made the decision not anything inherent to .277 vs. .284. Let's look at Federal factory loads... .270 140 Nos Accubond vs. .280 140 Nos Accubond vs. .280 160 Accubond. The Accubond has some of the highest BC of any hunting bullet and the heavier than you can easily get in .270 160 weight is represented. I don't see a significant advantage, at least to 500 yards.

Velocity 500 yards:
.270 140 - 2075 fps
.280 140 - 2096 fps
.280 160 - 2003 fps

Trajectory (500yds w/200 yard sighting)
.270 140 - -39.3
.280 140 - -38.2
.280 160 - -43.1

Wind Drift (500 yds)
.270 140 - 17.4
.280 140 - 17.4
.280 160 - 17.2

How about the 162 A-Max at around .630... or the 168 Berger VLD at around .650? I know the difference is negligable when using the Accu-Bond... but it's the option of the high BC bullets that make the .280 a bit more versitile. Apples to Apples they're the same gun, but it's the availability of 7mm Oranges that make this argument a bit more colorful. ~JT

I'll stay out of this entirely, but of course - THE .270 RULES!

NO! The .280 Rules!

You are comparing match bullets to hunting bullets. If you want to say the .280 is a better long range match gun because of super high BC bullets, then I would agree. My understanding is Berger is working on this problem.

In any case, I would personally rather hunt elk with a 140 partition out of a .280 than a 160+ VLD, A-Max, Matchking, etc... For that matter, if I was going after a 1 load for long range deer I would rather it be an Accubond than any match bullet. Match bullets may kill deer very well, but the design parameters are targets not game. Other guys may have a different opinion based on long success with match bullets on game. I am fine with that, but to me it's not a good comparison for hunting rounds. Anyhow, I just ran the numbers for a 162 A-MAX at 2850 & 150 SST at 2900 and here is what I came up with (200 yard zero, 500 yards):

.280 2170 fps, -39.2" drop, 13.6" wind drift
.270 2087 fps, -39.9" drop, 16.4" wind drift

At 300 yards, the advantage is less than an inch in drift .2 in trajectory. I'm not saying the .280 doesn't have any paper advantages. I'm trying to quantify the "advantages" with unbiased data vs. blanket statements. When I do so, the advantages are very minor which is why the majority say the .270 & .280 do the same thing in the field.

I had the choice when I was building a 1903 into a hunting rifle. I just couldn't see building a 1903 into a .280 instead of a .270, though. Nostalgia just wouldn't let me do it. This may be true loonyism, but that's o.k. I never denied being a loony.

Okay
This thread has convinced me- I am going to build a wildcat in .2805 caliber, exactly between the 270 and the 280, hopefully so I can have a cartridege with the killing power of the 280 but with the lesser recoil of the 270-
Should I neck the 270 case up to .2805 or should I neck a 280 case DOWN to .2805?
Necking the 280 case down would give me more case capacity, but certainly shorter barrel life.

I will be using sling swivels made of depleted uranium, and since I will be making my own bullets, probably between 135.678 grains, and 135.765 grains.
The main use of the rifle will be on Sitka deer at ranges up to 30 yards.
I am selling a 29 BS to raise money for this project if anyone is interested.

If you reload go .280Rem. If not most DEFINITELY go .270Win. many many more factory loads...............547.

I think I've heard that somewhere before!
