I am making my first practice attempt at seating .38 Special bullets. I am using Berry's plated 158gr. RN bullets- no cannelure groove. The Lee Manual lists a maximum OAL of 1.550 for .38 Special. It lists minimum length for copper plated bullets as 1.430. So to what depth should I seat the bullet? I have a factory Sellier and Bellot 158 gr. FMJ round which is 1.510 inches in length. Do you recommend seating to that depth? Thank you for any assistance.
