Happy Saturday everyone,
I used the search function but couldn't find exactly what I was looking for.
I have a new Lee .358 - 105-SWC mold. The boolits are dropping between .359 and .360. I sprayed them down with a good coat of silicone spray then started to run them through my .357 Lee sizing die. For lack of a better term, one side of the boolit is being rubbed smooth. Can you guys tell me what the heck is going on and how I should proceed? Why is it just on one side? I powder coat if that information is of any help.
Thank you in advance for your help.
