What is trim length in reloading?
In the standard calibres we have to trim because, as the case gets longer with the brass flowing forwards, the case will end up too long to actually chamber in the rifle. So, we trim the case back to a set distance to give us clearance in the chamber. The length we trim back to is called the ‘trim length’.
Is brass necessary to trim?
There is no set rule as to how often cases should be trimmed to length. Some calibres will need trimming more frequently than others. If you are using a ‘pokey’ load, and by that I mean a load that is near the top end of the pressure range, brass tends to flow more and so the cases will need trimming sooner.

What is the max length of a 308 shell?
I might be wrong on this one since I’m going off memory, but I believe the MAX length for .308 Win is 2.015, and the trim-to length is 2.005. So trim your cases to 2.005 and when they grow to 2.015 knock them back again. Chambers in factory rifles are very long, but I still trim, but as long as the shells are less than 2.015″ they’re good to go.
How long is too short for a 308 Win case?
I notice in the Lyman’s 48th edition that it gives the SAAMI max length of 2.015 for 308 WIN, but recommends a trim-to length of 2.005. A number of folks have said that 2.005 is too short. I am wonder how folks manage case length, so that it doesn’t exceed the SAAMI max. I neck size mine and only so it gives me .003 neck tension.

What size brass do you use in your 308?
Lapua states: 51.00 mm or 2.008″ as per their reloading guide! I have several 308’s, the brass stays with the gun it’s shot out of until the brass is no longer useable. I don’t swap brass between guns.
