expander ball on sizing die ?

[T-shooter]

T-shooter, Thanks for that explanation on setting the expander ball. I had just always laid my case on the outside of die and try to adjust it to Forster’s diagram pics, this makes more sense and will be more precise.

If you feel it try to lock up or get too tight, keep turning the ball lower by maybe 1/4 turns at a time.

When all else fails- read the instructions. lol

Ha, need to re-read instructions for sure. I’m pretty sure all Forster says is to set the bottom 1/3 of expander ball at the vent hole on their dies. Like others, I have been using the Forster decapping rods on my other dies as well without the vent holes. They run like butter with Imperial lube products.

Especially when you chuck the stem in a drill, and polish the ball with some Flitz, on a rag.

I always use the expander ball when sizing , Im not neck turning my brass and I full size to a minimum . What works for me is , I lube the inside of the necks with some RCBS lube on a Q Tip . The brass I'm using is on the thick side and it still will size smooth . I wet tumble so there's no build up , just make sure your lubing the cases . Removing the lube is another tumbling and after they dry will trim and chamfer , what I was have a problem with , being my brass is thick , when trimming with the RCBS TrimPro , I was getting a scratch on the inside of the necks , had to shave down the pilot a bit .
