Flute, schutzen shooters shoot a hundred round match with a single case.

You flat ain't gonna get case head failure at moderate pressure before the primer pocket or the side walls wear out. CARDBOARD will hold about 12,000 lup and you prove it when you fire a shotgun. A .38 Special or .45 ACP target load only generates about that pressure and they have a nice strong brass web. That web can loose 2/3 of its strength and still hold.

I toss bottleneck rifle cartridges the third time they need trimming. That's 6-9 shots with cases operating at 55k CUP. Straight wall cartridges operating at less than 20K, I shoot just short of forever.
