case trimming

[base64]

I have some unfired IMI 7.62x39 brass do I need to trim the cases the first time I load them??

I dont think so check your book for your shell length . Isnt cheaper to buy it in bulk? Thats what im doing only on that round.

Have you measured the OAL to see if it is within spec?

It's definitely under OAL and even 'case trim length' as stated in my manual, so I guess that means I should trim it as it becomes longer than this?

I have tons of surplus yugo ammo, and yes it's pretty accurate, but i'm hoping to push my mini-30 a but further and try to get some better accuracy with custom hand loads and using SP rounds should make for a great hunting rifle.

I'm sorry, I ment "case length". As long as you are under max, you're fine. If you are loading for precision, I'd suggest FL sizing all of it and then, trimming it all to a uniform length. But, I doubt that will do anything noticable since it's for a mini insteady of a precision firearm.

Ya case length is also correct on these, and is exactly the same length as my Yugo brass (which is also shorter than SAAMI specd case).

I think I'l load em as it is, I know this rifle is only so accurate but I sure am having fun! Soon, I'll be loading .308 to see some real accuracy!

Yes check them.. Weather if its new or not, it'll stretch when you size them.
