KabluewyForming 6.5 Grendel from 7.62x39 brass?
Is it practical to make 6.5 Grendel cases formed from 7.62x39 brass?
I'm just wondering how difficult this is to do. It may be worth it, if not difficult, especially since I have a bunch of the 7.62x39 brass.
Thanks,

Shouldn't be difficult. Many of my 22PPC cases are made from 7.62x39 cases. With good brass and dies it may be a one shot size operation.

steve4102Pretty simple, run the x39 brass through the Grendel FL sizing die. Load and shoot either with bullet or the "Cream of Wheat" method to fire-form.
If you do decide to do this, understand the x39 brass converted to Grendel has significantly less case capacity than true Grendel brass and you must adjust your loads accordingly.
Once at a Gunshow; I saw where a Dealer was selling .401 WSL made from 7.62 X 39 m/m cases.

SmokinJYou end up with a donut at the base of the neck, but other then that it isn't hard to do at all. The load data is different for 7.62 brass mainly because of the large primer..

I'm sure the larger primer can be a concern but in the .22PPC I've yet to realize it. Perhaps Alf can help us out here,
