Thanks of all the great input.

My reloads are not too long. 1.045 average and all have an OD of .375 at the shank of the bullet but grow to as much as .387 near the base. At the same location that factory ammo is .380 OD. Probably just need to take it down and set it up from scratch again.

I haven't used my 9 mm dies for a few years because ammo was so cheap. I assumed they would be good to go since they live in their own tools head. I should have been more careful.
