Do you start a new barrel with new brass?

[codym]

I have a new barrel but about 200 pieces from the previous barrel. There’s a bit more freebore on the new barrel running the same dies and bushings and the brass was amp annealed each firing. I have 300 pieces of brand new brass. How would you proceed

If it chambers then what could be the issue? Freebore is past end of the neck and should have zero to do with the brass. As long as both are SAAMI chambers (that is, not a custom tight chamber) the brass should chamber fine (after resizing, right?).

Have you tried to chamber the brass in the new barrel? If not, give that a try. I think you will be fine.

I would fire form the cases if it really concerns you.

I guess that was my not well asked question of the old brass has 5-6 firings on it do you think it will fully ff to the new chamber

Run a few through your reloading regimen and find out.

Why wouldn’t it? You said you annealed it every time. That means it’s soft in the area where fire forming is important.

I do new barrel/new brass

But I typically run a 100 round box of Lapua brass. So I typically have more firings on them

Just a question bud

If the chamber was done with the same reamer you should be able to use the old brass. If it was a different reamer fire the old cases through the new chamber to see if it has any issues, clickers etc. if not good to go.

I run brass until the primer pockets are junk. And the last couple of years I have been buying and selling quite a few different setups as I try to figure out what I like.

All that to say, I have a lot of 500 6br lapua brass that has been through 3 different barrels and I just recently converted it to 22br for my newest experiment.

My first barrel was on the looser side and when I swapped to barrel number 2 I had to go back and bump shoulders further to fit in the chamber.

If it was the opposite the brass would just have to be fire formed to the larger chamber. Not at issue, especially with you annealing.

Running through some brass now that was 4x in my old 6arc barrel and is now 6x in my new barrel from a diffrent company. I had to toss 2 peices that wouldn't size enough in body diameter to diameter to easily chamber in the new barrel. My 223s and 20 practical mostly eat 1x fired LC from many diffrent unknown guns.
