Of the last 168 reloads I've got 12 pieces with the neck splitting. I thought maybe it was associated with my latest barrel so I measured the neck after firing (.294) and after resizing (.287).
A little history, I lost most of my reloading info in a computer crash but I started with 180 pcs. of AA brass and used just under 900 primers reloading for the Grendel. In a perfect world that's 5 reloads per piece but I've lost a lot of brass to load development, some were a little hot and wouldn't chamber after resizing. I have 75 cases left. Now factoring in my the attrition rate, I guestimate the remaining pcs. have at most 10 reloads on them.
The neck splitting started in my last two batches of reloads. Is this just another case of reality not meeting expectations? I've read many time on the Forum "you should get 15-20 reloads using AA(Lapua) brass". Any thought or advise is welcome.
