I've been loading 12 guage light loads for the past several months without a problem. Last week I bought 500 Winchester AA gray Super Handicap hulls supposedly once fired. Of the first 25, I had two misfires. I measured the primer depth on the two misfired shells and found the depth to be .025 and .027 deep. The firing pin made a good dent but apparently didn't strike hard enough.
I loaded another 25 and was carefully with the primer seating pressure. I measured each primer depth and most ranged from .006 to .010. A few were more and some up to .018 deep. I had one misfire on this batch that's primer depth was .016 before being struck by firing pin.
What is the permissible primer depth limits? Is there any way to check the case before wasting time reloading it?
Before obtaining the Winchester AA hulls, I've been reloading Remington and a few Federal hulls and didn't have this problem. I'm using Winchester 209 primers.
