I have a new RCBS .310 sizing die that leaks lube out the top of the die when installed in my old Lyman 045 sizer. Do all RCBS dies do this even tho they are supposed to be interchangeable? Kinda aggravating cause it just seeps a little right at the front where you place a boolit to be sized. I've tried locking the die down with the set screw at different depths and all to no avail. When a Lyman die seeps I simply replace the die O-ring with a new one and the problem goes away. This is a new die with a new O-ring and it has seeped since first installed. Any suggestions would be appreciated.
