right @ 1.40 on the case length on the new brass. but after the 1st fire they are about 3-4 thousanths shorter after the form-fire
my seater Die crimps and I just raise the Die just a tad bit higher so it will not.
Sierra lists the trim length as 1.360". My Redding dies are crimping those and screwed down tight will put too much crimp on them. Just thought I'd let you know. The ones that didn't crimp were 1.350 and 1.330. A couple of Ooops cases I messed up and forgot about. You can call Redding as they were going to shorten my dies if I wanted to send them in. They were very helpful and I had to call them back and admit my dumb mistake.
