Since you have a 1:8 twist I'm assuming you are considering 130+ gr bullets. I spent some time working up loads for a bolt action 6.5 Grendel with a 22" 1:9 twist a couple of years ago and my opinion is that you don't have enough boiler room for 1,000 yds. I was only getting around 2,700 fps with 100 gr bullets and best accuracy was closer to 2,500 fps. It isn't a bad cartridge, but 600 yds may be it's limit. nhk

Well.
You can shoot 1000 yards with a Grendel. But it isn't the ideal cartridge for it.
Some of the Grendel supporters try to build it up like it is the wonder cartridge of the century.
But it isn't.
The 6.5 Grendel just doesn't have the case capacity to shoot the longer bullets effectively.
If you look closely you will notice that NOBODY is using the Grendel successfully in 1000 yard competition.
HOWEVER if you are going to shoot it at 1000 yards then you will need to go with the highest BC bullet you can find. Seat it as far out as possible, even to the point where you have to single load it because the OAL is to long for the magazine.
Then load it to the ragged edge of pressure. But even after that don't be surprised if you find a few bullets going through the target sideways.
You might want to check the Grendel board http://www.65grendel.com/forum/index.php?
About half of those guys don't even own a Grendel but the other half who do have a lot of experience with the cartridge. They should have a lot of load data.
Several guys on the different forums have tried the Grendel for F-Class and Service rifle competition but have abandoned it for bigger cartridges. About the smallest cartridge that you can get away with for 1000 yards in 6.5 will be the 6.5 BRX or something similar. They will hold about 5 or 6 more grains powder than the Grendel.
Also try the 6mm BR forum http://www.accurateshooter.com/forum/
However if you neck the Grendel down to 6mm you will have a smoking service rifle called the 6mmAR http://www.6mmar.com/ cartridge that will shoot better at 1000 yards than the 6.5 Grendel.
Count yourself lucky. You could have bought into a 6.8 SPC.

Ted. From your comments I feel that the 6.8 is not that great. I've been thinking about getting a 6.8 barrel for my Colt AR, but am still not sure. What do you know that I don't and should know?

The 6.8 is OK as a 100- 300 yard hunting cartridge, on animals up to about 200 lbs. It was designed as a 300 meter assault rifle cartridge. But as a long range cartridge it suffers from the same issues as the 6.5 Grendel and a few more.
The case capacity is within about 1/2 grain of the Grendel.
There are no really great match grade bullets for it. The only match bullets available in .270 (6.8) the Sierra 115 and the 135. The 115 at best has a BC of about .310. Because of the length of the brass any bullet seated at magazine depth can't be very pointy. So that bullet was designed with only about a 7 OG and just isn't slippery. The Sierra 130 is a better long range design but it will need to be hand feed. However the Grendel does have the advantage of having 10 or 12 good match bullets to choose from.
The SPC doesn't have the advantage of the great Lapua brass that the Grendel does.
I think that Remington has quite making brass for the SPC but you can get new Lapua brass for the Grendel and it is as good as they make. Also the Alexander Arms brass is actually Lapua brass with the AA head stamp.
So it is looking like the 6.5 Grendel has withstood the test of time a bit better that the 6.8 SPC. And because of the availability of a plethora of match grade and military grade. 6.5mm bullets it is also a more versatile mid range cartridge.
The 257 Ted is fire formed on 6.5G brass and it is really good stuff.

This is a little off the subject, but I was impressed with a friend's 6X6.8 SPC in a White Oak upper with a 24" match barrel. He was shooting 3/8" groups at 100m first time out with it. That may be a good medium range cartridge on an AR platform. nhk
