Re: WTB 6.5 STW Dies
Unless you have to have a custom made set, this is what I would do.
I would buy a Redding Type S full length sizing die and the appropriate bushing for your 6.5 neck and adjust the die in your press to only size it enough for your chamber. This is in stock at Midway.
Then I would buy a 7 STW Forster Micrometer seating die, and as long as you are careful with the initial entry of the bullet into the case mouth it should do quite well.
This is in stock at Graf & Sons.
