What are you doing for the dies?
280 Ackley Sammi bushing dies?
Reason I asked, I did two custom reamers based off of the 280 Ackley Sammi, just a change in the neck diameter, shoulder in the same spot, 25-280 and 26-280.
I used bushing dies to go down, but hadn't considered going up with them.
I like big fat slow bullets, this intrigues me.
32-280 Ackley sounds nice
