My .300 Weatherby seems to like hot loads; running Berger 210's at over 3000 fps (80.0 grains of 7828 .005 off the lands) I primarily use Weatherby brass and after 4-5 shots the primer pockets are pretty loose. I know the conventional wisdom is the brass is dead at that point, but why? Being a little curious I got my digital calipers out and took a few measurements.
Here is what I come up with:
.2100 (diameter of unfired Fed 215 primer)
.2080-2100 (diameter of a loose primer pocket)
.2060 (diameter of a tight primer pocket)
My question is why is the brass dead, if it is, when the primer pocket is loose. As long as the primer will stay in the pocket, good enough right !! I neck turn all my brass so it is not getting worked as much as a FL sizing would do. Anybody tried to "fix" the brass so the pocket would hold the primer?
