Here is my current understanding (probably totally wrong) and what i have done. Just started reloading 308 and want to get my rounds as precise as possible. I took a case and cut a slit across the case mouth. Put in a 168 SMK bullet at the very tip and shoved it into the barrel. After removing I measured the length: 2.925. Did this 2 more times which the lengths being 2.840 and 2.925 (how is that even possible?). Is it to this that I add/subtract 0.0015 and test?
This is a lot longer than the recommended OAL listed which is 2.750 or so.
So what happens now?
