What are you looking to do? Do you want to go beyond 700 or do you just want something different? Are you doing a full custom or just want a factory offered rifle/caliber?

I built this with Biggerhammer's help. It should be very effective on killing deer out to 500 yards, at least. I haven't fired it yet, but with the muzzle break, recoil should be very light. Here's the specs:
6.5mm Grendel .264 caliber
1:8 twist 24" Blackhole Weaponry SPR Barrel w/brake
Nickel Boron bolt carrier
12" Fortis armguard
Rock River Arms 2-stage Match trigger
Magpul PRS stock and pistol grip
9-13" Harris locking bi-pod
Steiner GS3 2-10x42 Glass UTC rings

I would encourage you to contact BH for some help in building one to your own likes. It took some months to build

I couldn't be more thrilled with how it turned out. This all started with a Colt AR that was on sale at Sportsman's and how cheap the barrels are on these off-the-shelf guns.

I'll second the 6.5 Grendel/LBC

Ammunition is available and inexpensive. (until PMan buys it all)

And if you are into wildcatting there are lots of interesting options for the AR

Hard to beat the 264 Winchester. Killed everything from chucks to elk with it. Anything bigger is barrel burning hype.just remember, stay away from 24" barrels. Minimum 26", better yet go for a 28"! In 24", its just a 270WSM...

Look into 6.5 Creedmoor

In all reality you might want to look at a different chambering other than the .264 Winchester Maganum if your looking to improve upon your your current rifles performance chambered in .270 WSM. Right now for all purposes and hunting you already have the .264 Win Mag beat with your .270 WSM chambering.

The BC's on the .277 & .264 bullets in the same bullet and weight class are so close it isn't going to matter for your mentioned purpose and range. As a matter of fact the .270 WSM will out perform the .264 Win Mag with the same length barrel (24") and same weight bullet by 150-200 FPS which actually surpasses the .264 Win Mag.

This is a couple pics from Nosler 6th Edition. The .264 Win Mag was a "King" in its day and is a very capable chambering but when compared to the cartridge you already have (.270 WSM). It falls short due to the case design of the .270 WSM and the burn rates of the powders suitable for the WSM.

The .270 WSM as per the pages bellow is 173fps fast with the 130's and 216FPS faster than the 140's. When cross referenced with each other with the reloading information provided bellow. That's why the only .270 rifle I own is a Rem700 .270 WSM and its hell on Mulies.

If you must have the "Bigboy" chambering, the 26 Nosler would be your daisy.

I would opt for a 1/2 MOA capable AR chambered in .264 LBC and enjoy it.

Blackhole Weaponry flat has their 8 twist .264 LBC's barrels dialed in! Bellow is a example(Pic) of the Blackhole barrels performance @ 100 yards from one of my 18" AR's chambered in .264 LBC. Building accurate AR's can become a addiction.

All are .264's

.264 Win Mag.(130gr)

.270 WSM(130gr)

Longer range?? How far??

300 Rum? 300 Norma Mag?

Another vote for Grendel here. Mellow recoil, long reach. Lot of 6.5 bullets available. Fits Std AR15 lower, so if you have a decent AR lower already, just build up a 6.5 upper and buy a couple mags and you are done. Only special parts are barrel, bolt and mags.

$300 Brownells barrel&bolt shoots .5moa if you do your part. All the rest of the parts are standard AR. I just mounted a PA 4-14x44 FFP ACSS ($280, Awesome piece of glass, rivals the $500-700 glass I have seen) on mine and zero'd on Sunday. Shot .527MOA until I jerked the last shot and ended with a 1.093MOA.

As long as PianoMan keeps his butt down south and leaves my sources of grendel ammo alone everything will be ok!!!

IMO I think your .270wsm is more then capable to longer than 700 yards. Shoot my lil .243 with 95gn VLDs has notched tags on muley bucks to 520yards with EXCELLENT results. Also shot my bear with the same load just under 400 shot it twice 1st shot was slightly back and 2nd dropped it like a sack of bricks. (quartered too, through front shoulder). I think you just want another toy. LOL

But, I really like the 6.5s, I reload for my brothers .260 and a buddies 6.5 Creedmoor and they are both excellent shooters with very little recoil.

Nice grouping Lamrith!

I think for ranges in excess of 700 yards and the gun you have now. I would say it is not the ballistics as much as the consistency. Your cartridge is capable of very long range use. Many are, but is the rifle? To me Long Range equals "CONSISTANT" NOT TRAJECTORY, If you can predict the point of impact, or not. Why is the 308 so popular for sniper or target work? its not because of high speed or flat trajectory, it is predictable.
