Thread: STRAIGHTENING A CROOKED BULLET

Bullet and neck runout issues can be due to movement in the presses ram, case holders and/or dies, as in not tightening down firm. I just did a good look over my press and found there's noticeable movement in the ram, gave it a bit of lube which reduced the play. The breech lock doesn't tighten down firmly when in its lock position so the dies can move a little, I tightened it past its locking pin and no more movement. Plus the cases have a lot of movement in the case holder, I fixed this by slipping a thin Oring over the case above the case holder which centers the case in the collet die. I neck sized a dozen cases and they were looking a lot straighter, tried to straighten out the crooked cases but to no avail. One thing I did notice when rolling cases on the table was some were showing runout at the shoulder.

Unless this brass is super rare/expensive, I'd chuck it and use new brass, it does not last forever despite what the AMP people want you to believe!
