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.

Thats exactly what I thought was happening. Isn't the trim to length 1.355 and not 1.4"?

I still don't have my build finished, but I did load some ammo with 1.355" cases.

I realize that you can do it however you want, I thought the spec was 1.355.

I think redding works on cases trimmed to 1.4" not 1.355" .
If you trim to 1.4" the dies will crimp.

I bought 1000 cases from Keith Davis and they are all trimmed to 1.355 - so my cases not crimping and I panic-ed.

Simple fix is to file/grind down a case holder by 0.045" to compensate. It is definitely way cheaper than having to re made a new batch of cases (and dump the short ones) or wasting money on different sets of dies.

After all, this are the fun part of having wildcat caliber.. you improvise

Jon,

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.
