25-06 Heavy Bullet Load Data

What do you mean 6.5 creed performance? A 25-06 with the correct twist and throat will destroy a 6.5 creed.
My creed shoots 140s 3000fps. Follow me for reloading advice. 
A 140 at 2800 is very reasonable with a 6.5 creed, so if I'm reading the chart correctly, it looks like you're trying to get a 135gr to the same speed.
This is some data I found on LRH where a guy was testing 135 atips in a creedmoor. This is also in a 24" barrel I believe.
I'm not trying to be a dick here, I have wanted a 25-06 for a decade or more, and never really looked into it that hard, but that data chart above seriously disappoints me. I figured a 25-06 would push that 135gr to 3200+. It's seriously not even capable of creedmoor performance. That's a 26" barrel and a ton more powder. Am I missing something? This is disappointing.

So Saturday I was able to get out to stretch the legs of my new 25 creed, previously only tested it out to 200 yards and
was curious what it would do at distance. My load was a 135 Berger at 2930 FPS clocked a month or so ago.
I shot from 400 to 1000 yards and with the rifle sighted at 100 yards I needed 6.5 mils at 1K, none of my 6.5 creeds
came anywhere close to that. Balistic calcs and my dope seem to align at 2990 FPS
A 25-06 case can hold 59 grains of extruded powder where a 6.5 creed will hold 44 grains, so I am very confident that a properly throated
25-06 will push a 135 way over 3100FPS.

A 140 at 2800 in a 6.5 creed is hot Staball in the only powder I see that gets there in sami pressure. I didn't check RL26.
A 25 caliber 135 is smaller in diameter than a 6.5mm 140, so it has potential to be a lighter bullet with a higher ballistic coefficient.
Rl26 is the powder, and you can get it to well beyond 2800. 3,000+ if you can believe the folks who have tested it.
And that's a 135gr A-tip. I haven't done the research, but I'd be really surprised if that .25 berger 135 has a higher bc than that atip
My 280 will easily do 2900 with a 139 with Varget. With H4350 or H4831Sc I would expect to be able to get 3100, in my 21" barrel.
Diminishing velocity returns as the powder column gets bigger, ya thats how it works. Welcome to reloading.
3 percent of 2800 is 84.
There is no replacement for cubic displacement.

The berger .25 135gr has a g7 of .334
The hornady atip in 135 6.5mm is .321.
So there is a slight advantage in bc to the .25

I can do math fella, the 3% I mentioned is the difference between the max velocity I posted above in the 6.5creed vs the (possible) velocity you mentioned above for the 25-06 (you said way over 3100, but nothing close to that appears in the data listed above, so I used your number of 3,100)..
No, you can't get well beyond 2800 in safe pressure. If you go to alliant's sight their loads for the 264 win mag for 140s are 3000fps or less. Any over pressure you can push with small case you can push with a big case.
No the A-tip doesn't have a higher B.C.
Now make a 25 caliber a-tip and spank it even worse.
