The 6.5 - 06 brass can be an issue. I'm uploading 25-06 brass in a full length sizer. Then once it's fire formed I can used a neck sizing die, These die's can be hard to find at times. It's not much more than a 270 in ballistics. While you can shoot lighter bullets than a 130 but you better get the twist in your barrel right for that. Once we got mine dialed in I was very happy with it, but it did take a while. I ended up with a 140 ballistic tip that shoots terrific in it.

A 7X57 would be an awesome choice !
