I found LEE 6.5X.300 WSM
Dies on ebay, they are full length size dies.
I am using the Micrometer Redding 6.5 bullet seater, with neck bushings to
neck size only.
We are getting 3250 out of 142 SMK and 140 Berger Hybrids with 63.5gr H1000.
3500 from 107's.
ALWAYS WORK UP SLOW!!!! WATCH FOR PRESSURE!
NORMA brass is our choice, FED match primers
I seat .010 off the LANS, you can get too much pressure seated too far in or off!
