i've done this. back when Grendel brass was difficult for me to get, and 30 Rusky short was available in 5 gallon buckets for free, and i had more time then $. it's a LOT of work to do correctly. you have to do at least 2 neck anneals, neck turning, fireforming. and most 30 Rusky short is LRP not SRP. so your load data needs adjusting too. is it worth it? if you can't get 6.5 Grendel brass or ammo, yes. If you can get 6.5 Grendel brass or ammo. no. unless just for the educational aspect of it or if you just like to tinker, which is fine too. or like me at the time, lots of free 30 Rusky short brass. not lots' of spare $ to buy 6.5 Grendel brass or ammo. enough time and tools already on hand to do the job correctly. my opinion of course. everyone else's may be different.

Never annealed the brass but did have to run an internal neck reamer through the necks after sizing and then after the fireforming. Not sure why but those 7.62 X 39 cases (IMI and Remington) I had that were brand new would get a big donut where the shoulder and neck intersected. So, run a inside reamer through them and take out the donut, then get two more loads before the primer pockets opened up too much for it to be safe.
Guys used the 7.62 X 39 brass for hunting from what I remember because it didn't matter if they lost the brass. Back then real Grendel brass was very hard to find. Alexander would get one or two shipments a year and it would be gone in a week or two.
