30-30 Case trim length

[Boho]

I've always trimmed my brass to 2.028 or 2.029. I purchased some pre-processed brass that is shorter, anywhere from 2.023 to 2.025. The SAAMI diagram shows 2.039-0.020. I assume that means the brass can be as short as 2.019. Has anyone shot with brass this short?

This would likely fare better in the reloading section, however, give this thread a read. Note what NC Smitty has to say as well as RC. That should answer your question.

Thank you Reloadron. New to THR but not the hobby.

No problem at all and welcome to THR. I hope the link helps and maybe a kind hearted moderator will move the thread as they see fit.

30-30 MAX case length is 2.039".

'Trim Too' length is 2.028", or .010" shorter.

However, I have seen more factory load case length variation in 30-30 WCF then in any other caliber I have ever reloaded.

The shorter cases are perfectly fine to reload & shoot.

But you will have to sort by length and load each length lot separate to get a uniform bullet crimp without not crimping the short ones, and buckling the shoulders on the long ones.
