Anybody use WC844 or WC846 in a Grendel?

[chuckbuster243]

Hello,
I have 6.5 Grendel bolt gun (AR also) and I am working on a prairie dog hunt this spring. I have used both 844 and 846 extensively in 223 and would like to try it in the Grendel. Mainly due to cost and availability. I have several 8 pound jugs of both powders. I am looking at the 100 grain Sierra HP and some 90 grain Speer tnt's. So anybody that has tried them let me know how they have worked out and what kind of starting loads I should work with.. I have always in the past worked 844 with H335 shot over the chrony to work the lots speed and the 846 with BLC-2. Any info will be helpful. Matt

I used 846 with the 123 grain bullets. My load was 28.6 grains under a 123 smk in ppu case with a large magnum primer.it was a warm load so start low and work up.

I've uses 29.0 grains of H335 with 100 Sierra JHP and get good accuracy, sorry never loaded 844 or 846.
