Anyone with a Wilson Chamber Seating Die either uses an Arbor Press or something similar. Since I do ALL of my reloading in my shop (not on a range bench top) AND since I don't have a Arbor Press, I decided to use my bench top drill press. I quickly found out that I needed a piece of kit that would interface between the press chuck and the top of the Wilson Die. So, I found an old John Deere Combine bolt that was somewhat past it's prime and made a flat headed adapter for seating my 6.5 Creedmoor, 5.56, ect bullets. Kind of a shame to us a old square head 5/8" bolt, but it's what I came across first. I couldn't indicate this bolt within 20 thousands (slightly bent) so I first turned the shaft and then faced the top of the bolt to make it 90 degrees to the shaft. Tried it out and it works great.
