well, here she is in her present form....bear creeek BCA 47 upper, PSA MOE blemished lower thaat i cannot fin d a blemish on, and a PA microdot. Also have a Wolff extra power hammer spring on hand, as well as an enhanced firing pin for greater reliability with steel case ammo. As a bonus, the day before i got the rifle, i was tasked with cleaning out a deceased relative's ''gun room'' and among various other teasures found reloading dies and 3 boxes of brass cased ammo in 7.62x39. Although not a handloader currently, the acquisition of his equipment may inspire me to become one, espeically since he happened to have dies for almost everything i shoot aside from 6.5 creedmore and 7mag.
If you do plan to reload 7.62x39, I have had good luck with Accurate 1680 and H-4198 with Hornady bullets. I found H-4198 did better for me than the old standby 1680. I did the reloading primarily during the great ammo shortage of 2008-10 in order to have something to shoot. Make sure to crimp your brass firmly (I used the much maligned Lee FCD ) and do full length resizing though for any semi auto. I also check every semi-auto round whether pistol or rifle with a cartridge gage to ensure proper functioning but I tend to be sensitive to stuff like that after seeing the aftermath of someone blowing up a new Kahr carbine with their reloads from an out of battery discharge. Out of battery and bullet setback can be serious issues when reloading for semi-autos.
The only brand of reloadable brass that I had issue with a few years ago when reloading for an SKS was Fiocchi due to inconsistencies in the brass length.
