So I have all my reloading gear here! Finally. (Well, almost everything I need except components... enough gear to start playing with it, and I've got some brass to prep.)
So anyhow, I was hoping to get some input on whether this would be a good project.
I have about 700+ rounds remaining of Paki surplus 7.62x51 that is tremendously innaccurate (extreme vertical stringing) in my FAL. I have good reasons to believe this is being caused by large variance in pressure (and therefore velocity).
-As I said, of the rounds that make it on target, there can be up to 12" in vertical string at 100yd.
-Ejection is very inconsistent. Some cases are thrown far, and some just drop out the side. I even had one that did not cycle the action enough for the empty case to hit the ejector. This is on a gas setting that cycles better ammo... umm... very strongly and consistently.
So, what I would like to do as a "first reloading project" is see if I can get some of this ammo to a more consistent state. Would this procedure be possible? For each round (performed on 20, 50, or 100 rounds):
-Measure factory OAL
-Pull bullet
-weigh factory powder charge
-Assuming factory charge weights vary significantly, recharge each case with an exact average of the charge weights recorded.
-Re-seat bullet to an exact average factory OAL as recorded prior to pulling the bullet.
The biggest potential problem I see here is that I will not be getting any neck/mouth expansion before bullet seating as my plan does not currently call for running the cases through a sizing die. I'm not yet sure if I could do that successfully or not.
So, any thoughts? Does this sound like a reasonable project?
