[QUOTE="frankinaustin, post: 1082015, member: 71931"] For me, the tricks I have found to improve straightness (i.e., reduce the runout of a seated bullet) are: 1. When seating a bullet that is at or near max powder load, I seem to get more runout, esp when I hear that crunch when I'm seating. What I do is seat first by running the ram all the way up, then rotate the case about 1/3 turn and do it again. Seems to help. What I think is happening is the case is just real full and the bullet just needs some extra help to smash all the grains down. This doesn't happen when I'm loading a "tender load" or if I'm loading on ball powder. 2. If the above doesn't help, what i do is get a kinetic bullet removed (plastic hammer) and knock the bullet out about 1/8" or a little more, and then just re-seat the round. This will clear up a lot of wobbly seats. 3. I always clean my re-sizing dies and my seater every time I use them, as well as the shell holder and the top of the ram. I use a .308 swab with a 3 x 3 patch (for 12 ga shotguns) that I have sprayed with Berryman's Chem Tool just to make sure there is no debris anywhere. I use this process every time. Some cases just always load wobbly with a lot of runout. when I look real close, it seems like the brass material itself just isn't perfectly consistently the same thickness. Perhaps if I cared more, I would neck turn. But i just mark them with a sharpy and use those cases for foulers or for speed testing. With Nosler brass I will have 5 out of 100 cases that just always give me more runout than I want. For me, when I'm doing load development, I want to test rounds that are no more that .0025" of runout. If I get a .003" or higher, I try to fix them. If they wont fix, then I take them along to the range, but only to speed test or foul my bbl. I think the amount of allowable runout depends on if you are developing a BR load or a deer hunting load. Also, I think if you are loading bullets with a secant ogive -v- tangent ogive also need to be taken into consideration on your allowable amount of runout. BTW, none of the above really matters when I am flinching on the trigger, which, if I were smart, I would work to solve first. [/QUOTE]
