My understanding is the best thing to use is a PPC head (available from SSS IIRC) since the x39 is .447" vs the .473" of the .308 based cases. A .308 based head might work but I haven't tried anything to be sure.Originally Posted by handirifle
I'm betting they feed from the mag just fine but each rifle is different and may need tweaking.Originally Posted by handirifle
