Just a heads up for people
The Lee 4 die set in 6.5 Creedmore will not work for you if you are using a AR10
gas gun.. The full length sizing die will not set the taper on body enough to chamber
a round.
You will need a Short Base Full length sizing die such as Redding or RCBS
ask me how I know ? I have the same set ...its great for bolt guns however
