[QUOTE="Blackhawk, post: 2058481, member: 105459"] [B].0005" runout is truly wonderful indeed![/B] [I] I am curious as to how you are measuring your bullets T.I.R. ( total indicated runout ). I myself use the Horandy concentricity tool and have replaced the .001" indicator with a .0005" indicator and consider assembled rounds with less than + or -.0005" good enough. [B]True enough I must adjust runout as indicated[/B] from + - .0025" using a match grade bullet seating die to an average of + or - .0005"as indicated. This is not alawys the case but I do spin up each assembled round and check the bullets concentricity adjusting those that are in need and passing those that are .0005" or less. My procedure by making adjustments to the bullet itself as needed will yield a combined TIR total of .0005" to .001". and no more than that. Considering factory ammunition will allow a runout of .003" I consider my runout to be acceptable. OBTW I am a retried tool and die maker and have a lot of machine tools on hand that will come into play by using them for reloading. You know how it is, you need this or that in order to make it easier to perform your job and before you know it you have acquired 3 tool boxes that are full as well as a roll away that is also full of specialized tooling and jigs that you have made. But I digress. I look forward to see how you are checking your bullets TIR.[/I] [/QUOTE]
