I have an old K-98 8MM Mauser. The barrel slugs out at .317/.323. The barrel is shiny with nice grooves in it and a nice crown. I bought some 170gr non-checked, flat based bullets from Hunter's Supply sized at .324. I'm shooting low power loads with Unique. With the bullets seated just above the first lube groove, the OAL length is 2.746. Max length for this round is 3.250. Now then, the bullets are shotgunning out of this barrel. Can't even begin to stay on an 11x8” sheet of paper at 25 yards. I've tried two loads so far. 14grs and 13grs of powder. Max is 17grs. There is zero leading in the gun. In fact, it's amazingly clean after the 20 round sessions. It acts like the bullets are too small and are scooting down the barrel, but I would expect to see leading if that were happening. To the cast shooters out there, any idea of whats going on?
