One shot, blow the primer out, get new brass
It must be a rainy day to judge by the number of replies so quick.
I hope you start to feel better soon James.
I've had about 15 loads so far out of my Norma 7mm08 brass. I Full Length size every time (too lazy to get neck dies) and I size them down by 0.003" (shoulder datum) so that's minimal working. I'm starting to get a couple of split necks in each batch of 50 but have never had a case head separation. I haven't annealed, just because I can't. For me its primer packets loosening. After just 3 or 4 loadings some start to loosen up and a few more go each time so now the 15 reload batches have about half quite loose pockets. They still seem to shoot just fine so I keep using them. I mark the loose pocket bases with felt pen. I wonder if its because I always clean the pocket with the cutting tool.
From the .303 I got about 8 or 10 loads before heads separated. Had to pluck the case out with a we saw blade I carried around for velvet. I marked those cases with big felt pen rings around the body - who know what that did to the sizing ! This was with a hammer-in lee loader. Interesting, all those pockets feel real nice to seat into compared to the 7mm08 now. The separation problem hasn't come back since I got a new bolt head which Din built up with some weld to fix the headspace. Good action the old SMLE.
Cheers for the sympathy, I'm feeling better today, was just a passing cold. Better to stay home and keep the rest of the crew from catching it.
Im using some ex army Lapua 308 in my 7-08. God knows how many times I've loaded these. Tough brass. I always clean pockets too. Wondering if Im sometimes too aggressive with a little bit of brass shed each time, but it all works so I guess its OK.
Bloody Fridayitis more like it :P
