I'm posting this here because I rented the crowning tools from 4 D Reamers,Fred was very helpfull and fast to ship, ordered on Tues. got it by thur., called and talked to Fred for advice on crowning he was very helpfull in walking me through it. Did a 22 lr. first came out looking pretty good then did a 44 and it to came out good started the 308 and pilot would not fit turns out to be one for a 303 brit. call Fred up and gets 308 in the mail same day, you cant get better service than that.
