Who's playing around with a 6.5 Grendel bolt rifle?

[stacy]

I HAVE SEVERAL HOWA MINI'S ONE IN 6.5 GRENDAL AND A 7.62X39 BOTH HEAVY BARRELS DIP BOTTOM METAL B/C STOCKS THE GRENDAL SHOOTS LIGHT OUT WITH 90GR HP AND H-335 AND THE 7.62 DOES VERY WELL WITH .310 123GR V-MAX'S AND H-335

One of twin Borden BBs we put together but have yet to shoot, but can't wait! Just need the range to get open...ammo loaded and ready to rock.

And now the "Twindels" are ready to shoot!

I just picked up a Howa Mini in trade a couple of weeks ago. The guy I got it from had put it into a B&C stock and said he couldn't get it to shoot under an inch. I bedded the action and gave it a good cleaning then mounted up a 6-18 Nikon for load development. So far I am very happy with it. 85gr Sierra Varminter HP over 29.0gr of H4895 in Hornady brass at 2743fps. If only I didn't yank that 5th shot I would have had a wallet group from a rifle I picked up for a steal. The only bad thing is Sierra discontinued this bullet, so after the couple hundred, I have left its back to the drawing board.

Noooo! Don't share that with the world, they'll find out . Good shooting btw. Try 90tnt same load.

I have mine all finished now and will post a pic when I can. Made up some break-in rounds with extras for sighting in the scope. Loaded 123gr Hornady SST's over 30.0gr of CFE223 in Starline brass. Hoping to try her out this weekend...

Ruger predator bolt 8 twist
Two loads I use
123 Hornady ELDM..29 grains of 8208 XBR, CCI 450
107 TMK..30.2 H 335, CCI 450
Hornady brass

I never could get the 107gr bullets to shoot in mine, but its doing awesome with Hornady 123 ELD's. Getting the best results with Alliant Varmint and Accurate 2460. Currently I'm playing with some 130gr Sierras and those are working real well to but havent found the "sweet spot" yet with my loads.

Hey Lefty try 27gr TAC with the 123 SST and forgetabout it. ( X-Caliber 20 inch barrel )

16" Bartlein 8t
R700

Feeds perfectly from an AICS 7.62 mag. AA2200 with 95s produce 2950fps, 2.1mil to 420y, shoots under half minute at 400y.

The only thing missing from that gun is a grenade launcher.

What are you guys using for brass? I have been using Starline and running into issues with it "work hardening" and causing major issues with neck tension. I'm having to anneal it every third reload. All my other rifles using Hornady and/or Lapua brass I'm only annealing every 5 or 6 reload, but even then I see no change in performance but the Starline brass the accuracy goes to shit and my SD numbers go off the chart.

 

[Sandstorm]

I anneal every firing. Yea some brass does seem to work better than others in that regard. I use Lapua and Hornady for my Grendel reloads with no issues

Anybody shooting out of a 26 inch barrel? Mine is a 26 inch and I'm running 123 ELD's but tried some of the 123 SST's tonight and they actually group about half the size of the ELD groups, this blew me away. Curious what powders and speeds your getting out of longer barrels. What I shot tonight was AR Comp at 26.6gr and it gave me 2505 with the ELD's with 1/2 moa accuracy at 200 yards and the SST's bettered that a little more but a tiny bit slower at 2478 but with single digit SD.

The 6.5 Grendel is just a fancy name for a 260 Remington. So ask the same question for a 260 Remington. The 260 Remington is a great cartridge out to 1000 yards.

No it is not. The 260 Remington is based off 7.62x51 308Win the 6.5Grendel is based off of the Russian 7.62x39 and PPC case. You can not fit a Remington 260 into an AR15 platform at all but the 6.5Grendel fits easily. Different in every way other than they are both centerfire cartridges that burn smokeless powder and fire a 6.5mm bullet.
