So do all the redding dies have type m expander technology? Or when buying them do you have to look for a die marked type m?
Also my question on over resizing, do you just back the die out till the brass isnt resized enough to fit in the chamber gauge. Then screw it in till it fits the chamber gauge? If so how do you know if the neck tension is tight enough? Setback scares me in 9mm. I reload for multiple pistols so i use the chamber gauge instead of pulling barrels.
Or is it if its resized enough to use,neck tension is not an issue? Mine are set up per instructions die touch shell plate which seems like its over resizing the crap outa them,but i was worried if i back the die out to not oversize i would lose neck tension.
I bought the hornady headspace tool you recommend to do the min.rifle shoulder setback,why push the shoulder back more than you need,i get that becouse the neck will be resized no matter what i roll the shoulder back to.
But with a taper case such as 9mm , it seems if i dont resize all the way iam going to lose neck tension is what iam getting at. But setting up the dies per instructions and dropping them in the wilson gauge you can see theres to much taper. It seems way overworked you can see the rim of the case could be expanded more to to catch the rim in the gauge that it headspaces off of, the brass seems inside the headspce rim.
So if i set it up were i cant see the brass around the headspace rim and it still slides in and out of the gauge like its supposed to will my neck tension still be good?
