Gents, need some help. Just got back from the range today, and I had probably 2/3 of my necks split. This from my standard 308 load that I shoot all the time:
Full Prep Winchester Brass
178 A-Max's with a 10 thou jump
43.0 gr RL15
BR-2 primers
Rifle is a Remington 700 with a 24" Kreiger 10.
I have no idea what this round will do as far as velocity, I don't own a chronograph. No obvious pressure signs. Primers are flattened a little bit, but nothing to be alarmed about, I've seen worse. No sticky bolt lift, no ejector marks, no extraction issues. I've reloaded this batch of brass maybe 8 times. Nothing crazy.
Temps today were pretty brisk when I arrived, 33 degrees farenheit, no wind. I have heard about pressure sensitivity from RL15, but I figured that would be on a hotter day, not colder. I've been reloading now for over 20 years, and I've never seen this.
Does this sound like a pressure issue, or is the brass just done? I neck size only, with a Redding neck sizer. I don't see any swelling near the case head, and the pockets are tight as new.
Any input is greatly appreciated.
