How short is too short? 6BR brass

[atombomb]

Had someone give me a bunch of Lapua 6BR brass that he claims was trimmed too short. So what would be too short? Wouldn’t it grow a little with a few firings and sizing? I’d probably have to make sure there wasn’t a carbon ring forming in the chamber/throat…. but what are your thoughts?

Send to me and I will shoot it to see if it will grow. LOL

how long is your chamber? What is the length of the brass?

6br brass generally doesn't grow much... depending on how short they are, maybe convert them to Dasher

1.520” is the shortest bunch of brass, chamber is .135 freebore.

1.520 should be fine. I am just going off memory, but I think that is standard trim length for alot of chambers.

But I may be thinking of the 30br.

Don't fear short brass (unless the neck is so short it won't hold a bullet) Shoot it. Watch for a carbon ring.

Sounds like it was trimmed to the old original 6 br Remington chamber ( going by memory here, so...)

That mistake can certainly be made, ask me how I know. Fortunately I bought a rifle chambered in 6 Tall Dog and that brass was shortened a little bit more so a mistake worked out well in this case,

They are correct. The original 6mm Br Remington had a max length of 1.520".
the 6mm BR Norma came out in 1995 and increased length to 1.560"

I know this as I used to have a gun built in 6BR in 1992 and had the Remington chamber. But it was rebarreled in 1998 with the norma chamber. Other than a possibility of a carbon ring, you should have no problems.
