[QUOTE="mountainman, post: 487067, member: 30120"] put your fired cases in your trimmer and turn your outside case neck walls down to the same thickness. Make sure you lube the inside of your cases before you resize, should solve your problem. Thats what I do and have no runout problems. Think about this, If you have a runout problem, and you straighten it out by bending the case(shoulder,neck) the bullet is now offcenter of the case pointing at the rifling at an angle, slight but at an angle. Can't help accuracy. When fired, the case will straighten out and if it does before the bullet hits the rifling you gained almost nothing buy straightening the runout and if it doesn't straighten out before the bullet hits the rifling, then the bullet goes into the rifling crooked. Again, cant help accuracy. If your setting your bullets shallow it may not be a problem correcting runout, just a matter of your setter stem doesn't match your bullet point. Correct or different setting stem should help. I have better luck by turning my neck wall to the same thickness before sizing and seem to get more even neck tension through all my cases. Whichever one of my cases has the thinest wall, then thats the case I turn all my necks down to. Yes It will shorten case life,(neck splits) but all my guns shoot real well. Also I should add that I trim cases the same,uniform primerpockets,deburr flash holes, choose cases that weigh close to the same as well as bullets and weigh powder to the 1/10 gr.This works for me.
