For those of you that use or have used 7.62 x 39 converted brass.
My x 39 Brass has less capacity then my true Grendel brass, so working up loads is a little more involved then just following published data.
In general, how many grains do you reduce the powder charge compared to reduction in case capacity per grain?
For example, My Grendel brass has 36.6gr H20, My converted IMI x 39 brass has 33.6gr H20 capacity.
BTW, I was cleaning my reloading room and found two (2) 1000 ea, bags of new IMI x 39 brass and I plan to convert a lot of it to Grendel.
Thanks.
