Hi folks, I'm yet another newb to the reloading forum here but I've been lurking quite a bit over the last few months as I've been getting my bench set up. First I'd just like to say hi and thanks for the wealth of information that can be found here in this forum.
So last week I finally got everything together and started prepping and loading .40 cal. pistol using my WWB brass. After decapping, the OAL of the brass is consistently from .840-.843. Both the Hornaday and the Lyman manuals say max length of .850. Should I be trimming these to a uniform length prior to loading and seating the bullet?
Here's why I ask that. When I seat the bullet in my Lee carbide die I'm getting inconsistent COL ranging from as low as 1.120 up to 1.140. Max OAL says 1.135. I had to keep resetting the seating depth on the die. Am I doing something wrong here or could that have something to do with not trimming the brass?
I hope this isn't a stupid question, and thanks in advance for any help or advise.
