I agree with Austin. I did a little experiment a while back to project theoretical variations in oal on my 45 acp rounds. To make a long story short, bullet olgive variation was the culprit in inconsistant oal's. One batch of bullets would give me a variation of .006" and another mfg's would give me .003". Although I've not run into it personally, I could see where an improperly matched seater stem could also give you variations, especially with SWC's.
