6.5 Grendel

[Md reloader]

AR Comp gave almost me almost identical results to 8208XBR if you can find that.

I have some AR Comp on order. I'm working with 123gr. What load data do you have?

123gr Amax, 28.5gr AR Comp, AA brass, 2.26 OAL (mag length,) 18" barrel, 2599 FPS & 8.9 SD (7 shot string)

Do you find the ARComp to be a faster powder for the Grendel with the 123s ?

AR Comp and RL10x have given me the highest velocities in my Grendel.

There is not much load data for Alliant powder for the Grendels. I called them and they only had data for RL15. And that is not to be found. I have some AR Comp on order to try. Interesting to see RL10X.

I've only used 8208 xbr and ARComp as a replacement for the Grendel and 123s, it is one of the few times I found a combination I liked and didn't mess with it. I've heard you can get higher velocities with some other powders, Leverevolution being one.

My best has been 8208 but curious about the ARComp

 

[K.E.C.]

CFE-223, Tac, Rl-10, all will give you speed and accuracy. But are not temp stable.

I saw a 20 FPS increase with ARComp vs 8208.

Thanks.

I run Accurate 2520 with 120 Nosler Spitzer and it make a 5-shoot cloverleaf hole and MV is just above 2500, I have found a load for the 8208XBR it seems almost Identical to the 2520. Oh and everything just drops like you turned the switch off.

This is why I use QL. If the powder is in the library I can calculate any combination whether published data exists or not.

I'm a little late to this thread, but H4895 also works great with 120 class bullets in the Grendel. I load 27.7gr H4895 (slightly above 'Max') and a Sierra 120gr Pro Hunter for my AR and the results at 100 yards are more than acceptable…

I'm about to give the Speer 90gr TNT a try with Benchmark and/or 8208 XBR and see what happens.
