Hi, I need somebody with experience or somebody who got across this situation to confirm or guide me. Today I was shooting my 338 edge, confirming drop chart and I got a strange situation. From 50 rounds fired I got 3 cases splits and cracks on the base area. I inspect very carefully every case prior reloading, without seeing any signs. I run 92gr H1000 at 2744fps at 5329 elevation, and THIS LOAD IS NOT HOT. THE HOT LOAD FOR MY RIFLE IS 93.5gr h1000 so I'm on the safety area. This cases was reloaded 10-12 times, and trimed 3-4 times No loose primer pocket, no hard lifting bolt, just sometimes hard extractind case.(this is the time when I trim the cases to the size) I do FL resize. As you see in the image around the base area I have light marks around base as a sandpaper marks around the case base. The splits is because of too many reloading? or a problem with the chamber? Any advise will be more then welcome!.
