Trimming and case length

[chase870]

Am I overthinking it? do you trim them to the length in the book every time

You don't need to trim until case length drops out of spec.

I don't trim until the case exceeds the listed maximum length.

no you aren't overthinking. It is a good idea to check them every time after you size them. Try to get them about .010 under max or less to keep your carbon ring minimal. They may not need trimming every time but they do need to be checked every time. As long as they are under you are good. If you let them get over the chamber can act as a crimp die and a carbon ring would add to the issue and if you are close to max pressure it could cause a spike for you.

Certain ammo goes through multiple firearms. I just run them through the trimmer each time. If only one rifle I'd probably just check.

Thanks for the info, I was starting to get tired or trimming cases to the book spec each time.

Hey chase check out little crow works. My uncle (60+ years reloading) talked me into one several years back. I plug it into a drill press and hammer out a big batch. I have a couple other trimmers but use this for brass that I shoot a lot. I have the WFT2 and housings for 6.5 CM, 6.5 G, 223, and a couple others.

WFT2 - Trimmer & Chambers

NOTE: This item by itself will not trim any cases. You must also purchase the WFT2 Trim Chamber inserts for the cartridges that you want to trim.
