BRX case forming question.

[Phil]

I`m guessing by now most are using blue box brass so i`ll base my question on that.

What length are your cases after fire forming???

Do they grow with a second or third firing???

Looking to spec. a reamer and looking for some input...

Thanks,

Phil.

My reamer is a .269neck.104f.b. Brass from new(blu box) gets trimmed to 1.540. 1st firing 1.520.2nd 1.528 brass is 99% after 2nd firing. Fireforming with 30gr of varget and odd bullets.

I get the same with my blue box 1.520 using 30grs varget with a 105 into the lands.
