If you send them a reamer print that would help . however reamers are not always as per drawn . If you could get 3x fired brass this would be best.I'm curious if anyone has any experience with Whidden's off the shelf dies? I had him make me a custom FL die for my 20 Vartarg, but am curious if I should go that route with the 6.5x47 I have coming or just get his in stock die.
