I have a lot of molds but have not been casting for awhile due to a lot of business travel. Anyway I broke out a new mold the other day which is the Lee 309-113-F that I want to use for some light small game loads in my H&R 158 Topper 30-30. I couldn't make a decent bullet even though I did all the "assumed correct" preconditioning, etc. The sprue cutter seems tight some I am assuming the reason I was getting incomplete fill out is due to the overly tight cutter which keeps the air from flowing. Is that a good assumption?????
