After being gifted a 7mm mauser this past week, the rifle im building to shoot long range will no longer also be required to be a deer rifle, it's a .270win right now, and I would prefer to rebarrel it to a caliber that utilizes the same bolt face to minimize what I have to purchase to rebarrel it. I was thinking about a 6.5 creedmore, seeing as how it's gets awesome reviews, but since I have a long action, I know I have more options. What would you switch to if you were building a dedicated long range, long action rifle.

I like the .270 Win., though you'd have better bullet selection with .280 Rem., .280 AI, .30-06, etc.

Good ideas...and give the .284-derived cartridges some thought also. In a long action you can can get a lot of powder under a long bullet. I'd think about 6.5-06 and 6.5-06 AI also.

I thought about a 6.5-284 but that's a short action caliber correct? There are so many I can't keep em straight.

280 AI or 6.5-06 hands down. I think the 280AI is near perfect.

6.5-06 sounds great. And the brass can be made from .270, 30-06, or 25-06. That's a nice bonus and there will never be a shortage of brass.

My only question is, is the 6.5/06 substantially better than the 6.5 creedmore as far as ballistics are concerned? I know there is factory ammo available for the 6.5 creedmore which I could use til I start reloading, and I don't do that currently.

^^That's right^^



The 6.5-06 is pushing the exact same bullet only quite a bit faster. The key tk shooting small and/or shooting far is ultra consistent ammo = hand loads. Assuming the rifle and optic are as stout, and consistent as possible removing that factor. All of this is about removing factors.

Well built rifle, check.
Base, rings, scope up to the task, check.
Ammo tuned to the rifle, and super consistent, check.
Shooter doing everything right behind the rifle, check.

What's the wind doing and how do we correct for it? The last factor we have no control over and can only learn to judge it and allow for it. = Practice!

If it were my action. I would rebarrel in 7mm, chamber in 280 A.I., load it with 162 gr A-maxes, or 168 gr. VLDs and never look back.

It will fit a short action, but in that case you have to seat the heavier bullets pretty deep. If you chamber a long action in 6mm-284 or 6.5-284, you can seat bullets way out there and get a considerably larger powder charge under the bullet.

My 6-284 is a long-action rifle so I can seat these 95-grain Partitions pretty far out. In fact, I think I can't even reach the lands on account of the chambering but it's been so long since I developed the load I couldn't tell you...I've only recorded comparator length so I can duplicate the load. I do believe that I could seat the longest bullets shallow enough to get plenty of powder under em.



One thing the 6mm-06 and 6.5-06 have on the .284-based cartridges is the ease of locating reasonably priced brass. Truth be told, I'd probably have selected 6mm-06 over 6mm-284 for that reason, but this particular rifle kinda fell in my lap so it's what I'm using.

30-06 with 208 amax or 200+ hybrids would be some bad medicine if you could take the recoil.

As usual, the 30-06 is ignored, but not for it's merits.

If I had it in the right stock, maybe with the right muzzle brake I think that'd be an excellent choice.

Interesting. Recoil really doesn't bother me too much. Although I do have a flinch I'm trying to get rid of. Which is odd. The actual recoil doesn't bother me at all, but I catch myself anticipating it anyways. But it's getting better thankfully. Timney trigger has helped.

if it could be anything & u want to load for it:

.26 Nosler

The .26 Nosler (6.5×66mmRB) is a rebated-rim centerfire rifle cartridge designed by Nosler and first announced in November 2013. It is designed as a modern 6.5mm cartridge, using recent advances in firearm technology to attain exceptionally high muzzle velocities (up to 3,400 ft/s (1,040 m/s)) and maintain an extremely flat trajectory. The overall cartridge length of 3.340 inches (84.8 mm) is the same as that of the .30-06 Springfield, allowing the use of widely-available standard-length actions. Nosler claims that the .26 Nosler is the most powerful commercial 6.5mm cartridge in the world: when loaded with 129-grain AccuBond Long Range very-low-drag bullets, the velocity of the .26 Nosler at 400 yards is nearly as high as the muzzle velocity of the .260 Remington.

6.5-06

7 Rem mag + 168gr Berger

Plain 284 or 280AI would be my first choices.

That would involve a new bolt. And 7 Rem Mags deserve 180's.

How does one get into a magnum bolt face? Buy a new bolt?

.

The 6.5-284 Norma specs call for a long action so the bullets can be seated further out, not taking up powder space.
I went that route for my long range rig, so far the furthest I have taken it is 790 yards, it will go much further though. The 6.5-284, 6.5 Remington Magnum and 6.5-06 all have almost the same case capacity.

a gun smith can open the bolt face and would most likely change the extractor....

Either get the smith to open up the boltface or buy another bolt. There are places like Pacific Tool and Gauge that sell Remington 700 bolts. there are probably others that do also.

And all nails "deserve" to driven in with 12lb sledge hammers!

280 AI or 6.5-06 or 30-06 would be my choices.
