Brass Trimming

Hi I have been doing some reloading for a year or so now, my question is when some of your brass starts to creep up on the SAMMI specs for max overall length, what is the best way to go, trim only the long ones as you need to or trim the whole batch to a uniform length? any thoughts ? thanks Scott

Trim all to uniform length. I generally go .010" under the nominal size.

I trim mine each and every loading to "a uniform length". My cartridges are not only uniform to the ones in the same batch; but all batches are uniform to each other.

I will chamfer new Lapua brass, fire once, then trim and chamfer to minimum spec. I will then shoot until it is about .004" longer, then trim.

Re: Brass Trimming

I have not seen differences in performance when length fell within specification. A thou shorter is OK and might give you another load before having to trim again, but not critical. I do make it a point to make sure all my brass is the same length in a given batch of reloads, for consistancy puposes.
