140-grainers in the 6.5-06
140-grainers in the 270W

What is the difference in ballistics out to say 550yds?

How do they fly... laugh

Who makes the 160 grain bullet in the 6.5 and what is it's BC?

Woodleigh @ 0.509?

BC .487 .277 140 grain Berger
BC .612 .264 140 grain Berger

Depending on the velocities you will not see huge differences, but my guess is the wind drift on the .264
You should have more velocity with the 270, but the higher BC of the 6.5 should have a sleight edge out to 550.

I don't use these cartridges, so i don't have a baseline on MV's

Regardless, the deer is not going to be able to tell the difference @ that distance-Dead is dead, if you put the bullet where it belongs.
I just popped a muley buck on Wednesday at 496 yards with a 6.5, using the 130 Berger=DRT! MV is 3095 fps.

Thanks Ernie I appreciate it!

I'm looking at which one would FLY better in regards to wind drift primarily at this point and I should've mentioned that
initially...I shoot a 270W/130gr, but I have the opportunity to purchase a 6.5/06 from a good friend at a superb deal!

Never shot a 140gr in my 270W before and was just entertaining the thought of how the 6.5-06/140-grainer would compare at that range...

Yep, dead is dead for sure...shot-placement is #1.... grin

BIG CONGRATS connecting on that MULEY!!! grin

Wind drift based on 10 mph wind at 550 yards

6.5 140gr @ 2800fps = 19.4"

.277 140gr @ 2900fps = 21.7"

This is assuming these velocities which appear to be near max according to the Hodgdon load guide

2.3" of wind differences.
I thought it would be close, with the 6.5 winning.
Now my choices would be upon which rifle is the most accurate and that you can shoot the best from field positions.

.............To get a real good idea, go to the Hornady site and find their "external" ballistics table.

Type in all the goodies: the bullet BCs, bullet weights, preferred rifle zero yardage, approx MVs, temps etc. Then compare the two calibers downrange at various distances for retained velocities, energys and trajectory drops. It`ll give you all the info you`ll need in order to make very accurate comparisons.

On another thread here, there was a video which showed Wayne Van Zwoll using a 6.5 Creedmoor (129 gr Horn SST) downing a bull elk at 603 yards with one shot.

Of the two for deer, I`d be more inclined to use the 6.5/06 along with some (my particular bullet preference), the Berger "hunting" VLDs. At 550 yards, that will be a very quick and deadly combo.

I'm thinking the 6.5-06 has a lot more potential velocity with 140s.

The little 6.5 Creedmoor makes 2800+ fps with 140s, in factory loaded ammo.

The Creedmoor has 53 gr case capacity.
The 6.5-06 had 68 gr case capacity.

In terms of the 'numbers' I would expect it would favour the 6.5 - a much more popular caliber for long range shooting / high BC bullets. The biggest difference would perhaps be that 270 Win is one of the most popular factory cartridges around, whereas the 6.5-06 is obviously (still AFAIK) a 'wildcat'. If you're already set for a rifle, and don't care about factory loads, then perhaps that won't matter to you. Otherwise, they will be pretty close in all things, as one might expect given the near identical cases and .007" difference in bullet diameter.

.....Yes! The 6.5/06 is more powerful than the Creed. I just brought the Creedmoor up because Van Zwoll used it in the video.

Out to 550 yards or more on deer, the 6.5/06 will be superior.

bigsqueeze, I wasn't referencing your comments, I'm just saying Hodgdon's data at 2800 fps is nowhere near the potential of the 6.5-06.

If the Creed can make 2800 fps with a 140gr, the 6.5-06 with over 25% more case volume should be able to make around 3000 fps with the right powder choice.

My standard load in my own 6.5-06 (26" barrel) is the 140-grain Berger VLD at 2950 fps, using 56.0 grains of H1000.

In the same length barrel, a Ruger Hawkeye in 6.5 Creedmoor gets just under 2800 with the same bullet and Ramshot Hunter. This is just about what the 1/4 Rule calculates the difference should be.

MD, your velocity of 2950 via H1000 calcs around 56K lbs-psi, per QL.

RL22, VV N560, Ramshot Magnum among others, look to have 3000+ fps potential, via 24" bbl, at 60-62K psi, and around 100-104% load density.

Now, how about some real world 270 Win MV's with 140's?
As it stands now, 150 fps more with the 6.5-06, will just make for even less drop and drift than before-Which is always a good thing.

MontanaMarine,

I gave up on relying on QL years ago. I tried a bunch of powders, including the three you mention, and never could break 3000 comfortably with any 140-grain bullet, even in the 26" barrel.

The highest velocity Nosler lists with the 140 in their 24" barreled 6.5-06 test barrel is 2906, with N165. RL-22 tops out at 2860. Now, those maxes are probably with the 140 Partition, which generates more pressure than most bullets.

Rl 17 and Magnum will easily take it there, not that it needs to.

I tried Magnum and it didn't shoot nearly as well as H1000. Haven't tried RL-17 yet.

As a follow-up, I did a search for all the pressure-tested data on the 6.5-06 I could find, plus a little extra.

Hodgdon lists 55.0 grains of H1000 as max with the 142 Sierra MK, which should be pretty close to the 140 Berger VLD: 2816 fps at 63,300. So I am already one grain over their max.

The highest velocity listed by Hodgdon is 2889 fps, with 49.5 grains of Hybrid 100V @63,200 psi.

Ramshot doesn't list the 6.5-06 but does have data for the 6.5/.284, which is just about identical in case capacity when bullets are seated out--and they are in the Ramshot data.

They list Magnum as getting 3070 fps with the 140 Sierra GameKing, with 62.0 grains at 64,000 psi. But with the 142 MatchKing they list 59.0 grains of Magnum as max, for 2900 fps at 63,200 psi.

All of the above data is from 24" barrels.

Obviously the velocity attainable is very bullet dependent, but still I am really doubting the QL results--and have for years.

Alliant doesn't list any data for the 6.5-06 or 6.5/.284, but I just did an in-depth analysis of their pressure-tested Reloder 17 data for a magazine article, and couldn't find the velocity magic that many people report with RL-17. In fact PowerPro 4000MR beats RL-17 in several cartridges, along with older Reloder powders such as 19, 22 and 25.
