Brass Prep, Using Once Fired Brass From Another Gun

[Earnhardt]

Never done this before...seriously
And my Google Foo, isn't finding much...

OK, I bought some once fired Lapua 6.5 CM brass from a guy.
It was shot out of his 6.5 CM (Tikka I believe)
My gun is a Savage LRP 6.5 CM, with a Bartlien barrel (SAAMI chamber)

I'll keep it short...

What brass prep do I need to do, to shoot the once fired brass from another 6.5 CM gun, in my 6.5 CM?

Thanks

Make sure an empty case fits into your chamber with bolt closed. If it does, assume your next firing will be fire forming to your chamber.

if not, resize them to your chamber specs and you are off and running.

Size it, OAL trim it, camphor/de-burr, uniform pockets & have at it...

I have about 1000 rds of Hornaday once fired brass I'm using. I check it's fit to my chamber and only size it if necessary. After that, it's fully fire formed and ready to go.

Thanks for the replies fellas!

One thing I have experienced is if the fired brass came from a chamber larger in diameter than yours, sometimes they seem to remember that. Even when using a small base die, sometimes they expand back to the point of bolt click each firing.

Anneal it will soften it an maybe help with new forming, worth a try

Do you measure you case head to datum when setting up your sizing die?

I would measure the OD of the fired necks on brass from both rifles.
I would measure the case head to datum on brass fro both rifle.

I the used brass you bought is a smaller fired case neck and a shorter case head to datum, then I would try to chamber a case prior to sizing. If it chambers, fine and size with your die set for your rifle's chamber. If it doesn't chamber, then size it with the die set for your rifle and check to see if it chamber.
