[Tim-o-thy]

Measure your chamber.

My smith told me what max case lenght should be on my 6BRA, but like you, I could not correlate it to the reamer print

 

[Tim-o-thy]

Measure your chamber.

You’re gonna have to forgive my ignorance with this. Can you point me to thread with instructions or lay it out for me?

The reamer print is. All that should be need
I don’t see how anything could change that what reamer do
The. Chamber should be the Same as the reamer cut it

Doubt it's gonna be an issue. Chamber length is something like 1.570 on all the reamer prints I've seen and typical fireforming length is around 1.550. It takes forever for the cases to grow, I didn't trim mine until 7 firings because they were all +/- 0.001 on fireforming and they grew less than 0.001 per firing.

What a let down. I thought this was about bra trimming...

If you have a Hornady (nee Stoney Point) "OAL" [sic] Gauge, you can make your own chamber length gauge as described here (for 6mm, requires a spent 22 WMR case):

Or you can buy the Sinclair Chamber Length Gauge (cheap) and follow the instructions:

You can also measure the chamber length using a pin gage of appropriate diameter, and a cleaning rod. Fairly simple, but requires using your noggin and a little arithmetic.

I thought he was talking about a Christmas tree and Mrs Santa Claus being naughty.

Thanks man I really appreciate it

The necks don't really grow on a bra.
I measured them all, found the shortest and trimmed them all to that length. Shoot em 20 times ...never needed trimming.

On fire forming the br case fit pretty good. So good A high primer stopped the bolt from locking up. Shoulders formed great.
