My shooting buddy and I started to set up RCBS dies to load his 7.62x39 today and when it came time for the seating we ran into problems. First the die was pulling the bullets out of the cases, and holding them in the die until it was taken apart. Also when we set the depth of the bullet it will go in and the powder pushes the bullets back out. You can see grooves on the brass to indicate that is what is happening. We crimped until it was bulging the nec, and started over again. I checked the Speer and the Hodgdon specs for this load. Speer shows 27 to 29 grains of H4895. First if you load 29grs. it fills the case to the top. With 27.7 it fills to the bottom of the neck. I have tried to readjust everything and watched the RCBS DVD over and over with no luck. With all the other dies that I have set up there has been no such problems. Any info. would help, but if nothing by Monday we are calling RCBS.
