[QUOTE="180pilot, post: 87380, member: 3897"] Men don't listen and women can't read maps :-) In my post it states the case cracked and leaked gas, (separation) that's what you are looking at. And, I assume the drop in pressure from the case head failure caused the incomplete seal of the neck letting gas by it. No other cases have done this. I've tried AA8700 and it shoots slower then Hornady manual. IMR 4831 with 139 Gr SST's,.. about right on with manual. Rifle is out of warranty, as far as Savage is concerned, I bought it in 2003. They no longer make that chambering anyway, ALREADY TALKED to them. There's many other things here to look at yet, finish on chamber wall, residue oil in chamber, brass hardness, barrel finish and dimensions etc. etc. I will neck size only from here on out. And getting barrel air gaged. IF I can't get the velocities I want, a re-barrel job on Savage is a garage project anyway, so. no biggy. I'll have a new barrel made, screw it on and start over.
