New Brass Prep

Re: New Brass Prep

It wont matter. Just load it and shoot it. Get back home and set the shoulder back

FYI Trim them after you resize.
 
Re: New Brass Prep

I just run em up to kiss the expander to bring the mouths back to round, Some other folks full length resize them. It's up to you.

As they are new, I figure the only thing out of spec. are the dented mouths. Thus I only fix what is broken!
 
Re: New Brass Prep

+ 1 for all of the above.

I don't worry about trimming until I've fired new brass in my rifle at least once, then trim to the shortest if for precision work. If for general shooting, just trim the longest to minimize variables somewhat.

After running thru an expander to round out any dents, you may want to lightly inside chamfer the necks just to make sure bullets get seated cleanly.
