I must be going nuts. I bought two boxes of PMC Bronze FMJ-BT in .308 from AmmoToGo when I was first trying to find decent practice ammo. And even before I floated and stiffened the weapon the PMC would hold close to MOA all the way out to 300 yards without sorting it by weight and OAL. The cases were nice and shiny just like any factory Match ammo. Nicely polished, no discoloration nor tool marks.
Now I just got a new batch of it from ATG and the cases have a greyish tint down to about 1/8 inch below the shoulder (wish I had a camera). There are no ridges nor tool marks of any kind, just the discoloration. But this batch patterns like a shotgun. I mean this crap WILL NOT EVEN GROUP at 100 yards. I literally thought my rifle or scope was broken. I checked all my screws and mounts (they were fine) and adjusted my elevation and went back to the Silver Bear to see if I was going nuts. The Silver Bear shot fine. So I adjusted back the "PMC Bronze Zero" and I could not even get a pattern. One round would land 2" right and 5" low and the next would hit 4" high and 10" left and then the next wouldn't even hit the paper! Unbelievable, considering how well the first batch of it shot.
So my questions are ...
Has PMC always been this variable, or is this just a really bad batch?
And just for shitzandgiggles ... if this new lot of ammo shows the discoloration in every single box but no tool marks from over-seating/over-crimping, why would the first batch look perfectly fine all the way up and down the case? And is whatever caused the discoloration likely contributing to the horrid accuracy?
Danke schon meine herren!
