I have a set of 40/10mm pistol dies, which I have used to load .40 S&W; I'm getting a 10mm Mod 20 Glock. I saw on one of the auction sites the other day a set of 10mm dies ($65.00). Is this something special or were these made before the 40 S & W?
I had a 10mm back in '91. Dies said 10mm and 40S&W at that time. 10mm was developed in 1983 and 40 Smith was developed in 1990. If you had a set of dies that were pre1990 I suppose they would say only 10mmAuto on the box. I see no reason why they wouldn't work exactly the same.
