Trim Length

[Hummbird]

Is there any where i can copy and print a chart of handgun and rifle case trim lengths ? I need 9mm / 30/30 / 30/06. i would like to find trim length / max/min and length when loaded min.max. Thanks

You can download Lyman's 48th reloading manual for free. It has max case length and trim to length.

I don't know of anyone that trims straight wall cases like 9mm. Here are a couple of links. You can always search for SAAMI number of the case you are working on.

30-30

30/06

Yep, never trim it.

I would think that it would be important to have correct case length on rounds that headspace on the case mouth. I have always checked case length and trimmed my 40 S&W.

Yes, get Lyman's 48th or buy the most recent edition
Also buy the bullet manufacturers manual for the bullets you use most

There's much more valuable information in the manuals than just reloading data sheets.

SAMMI's drawings are also good to print out for the calibers you use.

All reloaders should spend some quality time with calipers and micrometer and the reloading components.
It'll give you wisdom from your own experiences.

All cases should be trimmed if they are too long. If the cases are within specs or short....well.... trimming is a moot point!

This will get you anything you want to know.

Go buy a manual.
You won't need a 9mm trim-to. Handgun cases rarely stretch. Your manual will have the trim-to lengths for bottle necked rifle cases. Trimming is an 'as required only' thing too.
SAAMI drawings have numbers like 2.0395 - .020". That's for .30-30. It's the max case length(rounded to 2.040" in manuals) with a tolerance of -.020" and is usually about 10 thou less than the trim-to(2.030").
"...length when loaded min.max..." Given in your manual too. And it's measured from the pointy par of the bullet to the flat part of the case. No ogives involved.
