So. I'm having problems with neck sizing/neck tension. I just ran 50 cases through my Lee sizing die. Trimmed to length. Deburred. Out of the 50, 12 are so big that there is no resistance on the press lever when seating. The projectiles almost fall right through. (On 2-3 cases, the projectiles will fall right through.) I dumped the powder out of three of them, decapped, and resized. Of the three, one would take a projectile properly.
I took some measurements and found that the cases that won't take a projectile are .240+" and the ones that worked have an ID of 2.35 or less.
I processed them all the same way at the same time. Some RP brass, some Barnes. All have beed reloaded at least 2-3 times.
I feel like this is in my sizing die, although I loaded 50 rounds last week with no issues. What is the best way to trouble shoot this?
