just got a set of lee dies for the 7.62x54r in the mail today. ive never had lee dies before. first do they seriously expect people to use the scoop thingee it came with for weighing charges?????? the dies have little rubber o-rings under the lock rings with recesses in the lock ring for the o-ring. whats the purpose of that??? the text instructions they came with mentions crimping as part of the seating die but it was confusing. these came with a seperate crimp die does that mean the seating die crimps too??
