I've never used the 2 die set before. I have a Dillon 550B with the 30 Cal Luger RCBS 2 die set where station 3 seats the bullet and crimps the case. I am having trouble with the crimping. Not getting the crimp correct. Anyone have any input????? RCBS is closed on Fridays!!!!!!!!! Thanks!!!! Station 1 deprimes and sizes, primes. Station 2 adds powder and bells the case. And station 3 seats the bullet and crimps. No station 4. I was told this is what to get for the 30 Cal Luger for the Dillon
