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

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. :chuckle:
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. :tup: 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 ;)

300 Rum? 300 Norma Mag?
Post by: lamrith on April 03, 2015, 01:41:30 PM
$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!!!

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.

I assume you just mean to ring steel or target shoot to 1k? Grendel is good out to 1200+, but it's effective big game hunting range is <500yrds.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?
Would like to go to 1000. And it will be a full custom.
Trajectories for grendel are very very similar to 308 but with low recoil and less $ in powder and bullets. The numbers I ran show grendel being about .10-20/round cheaper. Recoil on mine seems no stronger than a regular 223/556 AR.
Hornady ballistics for ammo and velocities I am seeing is attached.

If you want to keep it easy to shoot without a brake you'll either need to go with a heavy gun or a smaller caliber. I'm not exactly recoil shy, but I can shoot a 13# 6mm BR a lot better than a 10# 300 WSM. It's extremely hard to be consistent (which is the key to any precision shooting) when you're getting rocked out of your shooting position at every shot. If you want to keep the gun at a packable weight (>10# for me) I'd look at the 6.5x284 Norma. I'm partial to the original 284 Win but the 6.5 version is arguably better. If weight isn't a big concern then go big!
If factory ammo or components aren't an issue, I have a 270 Ultra Mag reamer sitting in my drawer. Run that into a 30", 8" twist barrel with the Matrix 165gr bullet at 3400 fps and you'd be good to go! If you want fast, my 270 ultra moves the 140gr bullets at over 3600 fps. It's a shame that the BC isn't better on those bullets.

DANG GINA!!!!!
A 165gr .277 Matrix at 3400, makes a .264 Win Mag rate right there along with a Daisy " Red Rider ". :chuckle:

For long range shooting I prefer a brake on my rifles so I can spot my shots and make my corrections. you just need some hearing protection.
Post by: mountainman on April 04, 2015, 07:37:14 PM
It will be your gun, go with what you want, be it a Grendel or the Win mag. Its your Money and your gun, right?😊

I will hunt with the gun so I don't want it to end up to heavy. Also absolutely will not but a brake on it. Had one on one gun and my ears rang for a week after shooting a deer. I fine with some recoil. I see Nosler came out with a new 142 grain ABLR in the .264 with a BC of .719. Thought I might have something decent pushing that out of the .264 win mag around 3100 FPS?youll get much more accurate results running the g7 bc instead of the g1
G1 BC's are for flat base bullets. G7 are for boat tails, it will make a difference past 500 yards.

You should also consider the 6.5-06AI. It should get similar velocities as the 264WM but with less recoil.
:tup: A abundance of brass, standard bolt face and lower pressures. What's not to like? ;)

definitely considering this for my next build. 6.5-06 AI
