6.5 Grendel VS 300 AAC?

[LRRPF52]

I use .260 Rem for ranges out to 1100m for long-range field and military competitions, where I know I will be in the bipod-prone, fighting position standing, or other supported positions most of the time. It really starts to shine over other calibers at 500m, but it is not the rifle I want to lug around so much in the heavy barrel form that I have, even at 22". My Grendel is light as a feather compared to the AR10's with target barrels, and I can shoot the Grendel a lot with its lighter barrel without fatigue. The Grendel also doesn't suck a ton of powder when I load for it, so that means less trips to the store for powder.

When I have done 2-day long-range courses with a featherweight .308 dropped into a McMillan A4 stock, even suppressed, it beat the trash out of my face and head, and that was with 155gr Scenars. The gun still shot 1/3rd MOA all day long, since it is a Sako 75 .308 with an amazingly accurate barrel, but it was abusive over extended shooting sessions. Not so with the Grendel, especially when you go to a heavier barrel. It feels recoilless in heavy barrel format to me, without a brake. While it may be the slower cartridge for distance work, it is a great balance of weight, accuracy, and efficiency.

Grendel v Blackout...go with Grendel.

I have two Grendel hunting guns. They are more than adequate for elk.

Blackout would better applied to suppressed home defense (not that the Grendel is not adequate for that as well).

260 Rem is a good choice for hunting as well.

The 260 Rem is an under appreciated sleeper. It shows ballistics approaching those of the .270 Winchester in a .308-length case.

Similarly, the Grendel can to as well or better than the .243 Win with a .223 Rem-length cartridge. Its a surprising result, but you can check out a discussion of the comparison at http://shootersnotes.com/grendelmani...or-large-game/.

Joe,
That's funny that you mention .260 Rem versus .270 Winchester. I recently purchased two different projectile types for my .270, since there are match pills available now from Sierra and Berger. Sierra makes the .277 135 SMK, and Berger makes the .277 130 and 140 Hunting VLD's. I got the 140 Bergers, and ran both G1 and G7 forms through Berger's ballistic program. The .270 needs at least 250fps more MV to match the .260 pushing the 6.5mm 140gr Berger VLD, but the 6.5 has quite a bit less wind drift at 1000 yards.

That being said, if you really push the .270 to 3000 fps and faster, you can get under 8 Mils of elevation for 1000 yard impact, which is pretty nice, but I can do that with the .260 Rem and much less velocity, like I said. You can tell which is the superior caliber for aerodynamics by just looking at the 6.5's versus .277's. The .260 starts to deliver more muzzle energy and flatter trajectory at 500 yards when comparing the 140 Berger VLD's in 6.5 and .277. It takes around 60 grains or more of powder for the .270 to launch at those velocities, and a long action as well. At least I have some use for the H4831 powder I bought now in a case that can suck it up. The .270's attraction is that it delivers more mass per area of impact, so it will probably ring steel nicely. I'll see soon enough!

And guess which rifle I bought? The only problem with my BLR in .270 Win is an atrocious trigger pull.

Yes, I've already run down the possibilities for making it better, but even the Browning folks say that I've got the best that can be done given the design. Much of the trigger group moves with the lever, so the creep and heavy pull result from margins needed to assure safety.

I continue to be amazed at the accuracy reported by AR users!

I don't intend to hj the thread but I just got a BLR take down I'm .325 WSM and it has a trigger that you need three fingers to pull. I have a gun smith neat by that says Thai can make it better, when I hey it worked on I will let you know how it turned out.

Probably the best designed .270win rifle is the Remington 760 or 7600, much can be done with that and a trigger job is super easy.

A pump action rifle with free floated bbl, what is there not to like?

Besides having an action nearly as fast as a semi-auto.

We are getting nearly 3200fps on a 130 SST with awesome groups. The Remington 760 is a slick old gun if you know how to tweak it just right. Plus you do not have to break your cheek weld while firing and tracking for another shot is needed.

3200 with 130 gr? Sounds interesting --

My dad taught me to work both bolt and levers while keeping the rifle in position, including the cheek weld.

Took a bit of practice, but the actions got a lot smoother too!

Here is some interesting info for you then, I forget the powder my friend loads for our .270win's but it might be this or something close.

Hornady® Superformance™

SUPERFORMANCE ammunition is loaded with proprietary propellants that increase the velocity ratings up to 200 feet per second compared to other popular brands. Because there is no increase in pressure, regardless of the caliber, there is no increase in felt recoil but there IS an increase in efficiency and high speed performance. From sub-zero arctic temperatures to almost unbearable desert heat, SUPERFORMANCE ammunition can withstand any hunting habitat.

Coming back from the 270. I am going with the 6.5 Creedmoor its going to be a bolt gun so I do not have to worry about the increased size of a AR10 platform also the Creedmoor is nearly a ballistic twin of the 260, will feed consistently from 308 mags, and takes the same bullets I already load my Grendel with.

If I end up needing any more gun then that I have a 30-06 witch will and has taken most North American game, and if I still need to step up its going to have to be in the 375H&H class.
