[QUOTE="Chopaka81, post: 384566, member: 9217"] I did not make that mistake. I am using twice fired neck sized brass that has been sorted by weight, trimed to length, necks turned, primer holes uniformed, and flash holes deburred. Bare in mind I am not bumping the shoulder of the brass, therefore in my little brain the differences in individual ogives of the bullets and slight variances in case length should influence the "overall" measurement of a seated bullet since the distance between the ram and the bullet seating die is fixed. I provided the link to the lock and load from Hornady since it was the 1st link I came to. I apologize that some did not know I was using an ogive measurement insert. My bad. Basically we used the lock and load to eastablish the location of the lands, then used an 30 cal ogive measuring insert with the lock and load to deterime the overall length. Sounds like the +/- 0.003" deviation is just the way it goes and I will have the live with it. Regarding the suggestion that I pay close attention when seating the bullets and using a consistant stroke, I have been doing that and it has helped. FWIW, The reloads are not compressed. Thanks for the input guys, I was mainly worried about my press being out of whack, sounds like for "utility grade" reloading the old rockchucker is fine. However, for percision bullet seating I may need to upgrade to a Wilson Arber Press. I guess that is the price one will have to pay to get from 0.5 moa to 0.25 moa. In my world of engineering I refer to it as dB $$. the price is now going up expotentially. [/QUOTE]
