Alpha 6BRA brass

[moorepower1]

I bought 100pc Alpha OCD 6BRA brass, before I read about all the issues specific to Alpha 6BRA brass. My question is, should I use it? I used the JGS #1 with .272 neck. It's use will be Pdogs and local club matches, so I don't "need" max velocity. I should have done more research before I bought them. I also shoot a 6br, so I was going to use different head stamps. Thanks.

Call Alpha and speak to them…. Have that reamer print in front of you and /or send a copy of the print and ask.. they will respond. It is great brass when you have the correct mix, chamber / sizing die …

I have 4 firings on Alpha brass with that reamer. I use a Harrell's 3.5 die and don't have any problems. You need to have a small base die to avoid clickers

Measure a fired piece of brass out of that barrel the measure the alpha brass with the bullet seated you will want the alpha brass with bullet to be at least .0015 smaller.

Yep, a Harrells die dialed me into my Criterion 6BRA chamber with both Alpha and Lapua brass. Send them some 3x fired brass and they'll send you the right die. Mine's a #2, for instance.

I have the same reamer, and Alpha brass didn’t work for me.

I think the same applies in the 6/25/6.5x47 cartridges. Got a barrel chambered with Alpha reamer and once-fired Lapua can't be sized enough in a Micron die to chamber. Alpha brass works fine.

The first firing of Alpha 6 BRA brass "might" give you some bolt lift pressure but after that it's been great in my rifles.
Because Alpha (out of the box) is a little smaller in circumference at the base than Lapua it needs a firing or two to expand fully to a non Alpha reamer chamber...After that my Micron die handles it perfectly producing easy extraction.
A good tip is to rough up your barrel chamber with some abrasive cloth ( if your gunsmith hasn't already done this ) which helps new brass "grab" the chamber walls, reducing bolt thrust for the first firing.
Once your cases are fully expanded it should be plain sailing!

6/25/6.5x47 alpha brass works fine in a non alpha spec reamer
