86thecat I cannot send cases back to Hornady due to import/export laws But Hornady have made arrangements with the local distributor and I have sent the cases to them.

when reloading the 40 odd cases that had no problems neck pressure and seating are fine it is only the primers that have popped out where I am having the problem and from just that one packet of ammo which has been shipped to the local dealer for further investigation.

I have been loading 340grn woodleighs to 2570fps and 400 gr frontier to 2385 fps in the 416 Ruger and have had no problem at all. It was just in the one packet of factory ammo that I had the problem.
