How much powder in resized AK brass?

[Grendel-Gene]

I have 100 cases of Winchester large primer AK brass that i have resized in the Grendel die.

I want to load it up to shoot "normally" in my Grendel and thus have it fire formed in the process. Since this is no longer an AK but not yet a Grendel, I call it the "Grenak".

Since there are no tables for this Grenak round that i know of, I am wondering how much BLC-2 powder should i use if i am going to shoot the 123 A max bullets seated "normally" at 2.250 inches?

Basically i am trying to make Grenak ammo that shoots as close as it can get to the Grendel at 100 yards.

Just want an educated guess really. Thanks

Gene

Not really apples to apples but I have done what you are wanting to do with 100g NBT's & IMR8208.

My full power load in true Grendel brass takes 30 grains. The heaviest non-compressed load I could get in a non-fireformed AK case (IMI) was 24.5 grains. It shot surprisingly well- consistently 3/4" MOA. I determined my starting load by filling the case to the bottom of the neck and reducing that by 3 grains. Proceed with caution, YMMV, et al.

26.5g of BLC-2 will do you well!!

Yep. 'Bout 6 miles from where I'm sittin'. It's probably a good thing they don't let many people in there..
