So I thought I new enough about reloading to make perfect ammo. But after reading all the stickys from tresmon, I'm a little confused. Should I still be trimming my cases to book length?

Re: when to trim cases?
You have 2 options. You can measure your chamber dimension and trim your brass when it comes within a few thousandths of that. Or you can trim to the "trim to" length and let the brass grow until it reaches the max length (usually .01" longer than the "trim to" length), then trim them back again. In my experience, case length variation isn't all that important, as long as your shoulders are bumped consistently.

Re: when to trim cases?
i suggest you get a chamber plug to measure your chamber
mine is almost 2.05. so i dont have to trim my brass for a VERY long time
after 3 firings my brass is only at 2.012

Aren't I bumping back the shoulder by full length resizing?

Yes full length sizing bumps the sholder back. I trim my brass to book spec & trim it back to that when they are close to book max length.

I trim before the bolt won't close.

Please advise on the "chamber plug" and where I can aquire one. I'm trimming my brass to "book" length everytime. Thanks.

Re: when to trim cases?
You can also get a Wilson case gauge for the caliber you are shooting. It has no moving parts, it will tell you if your shoulder is at saami length and if the brass is too long. You can use with a caliper to check your fired brass vs sized brass to get the correct bump. Just plop the case in and get a quick visual indication. I use them for my hunting cartridges, and an RCBS precision mic for my 308 field/target stuff.

Re: when to trim cases?
I think you meant to say Trim-to length and max length were usually different by .1" instead of .01".
