Got a problem, but I figure I ask before spending any money. We're reloading 308 for the first time, so I made 5 sample rounds, checked oal, cleaned them up, and I use a dillon case gage to check if all is good, and it is... So, I chambered a round in my friends m1a, no problem, then I chambered a round in my other friends rifle(r700) and its a no go. All five rounds will chamber in the m1a, and all but 1, didn't in the r700. So, I grabbed a handful of empty cases, ran it through the die about 3-4 times, and checked to see if it'll chambers, and it all did. Is this a die problem? Btw, we're using lee dies.
