Alpha Munitions 6mm ARC Brass

[StoneHendge]

I'm starting into my second box of 100. Primer pockets are looser, more like what I'm used to. I can use the pocket uniformer easily by hand.  As to the boxes, they are great, my only suggestion would be that they make the dividers a little shorter. As is, the dividers are slightly taller than a fired case so you need a little pick or something to lift the fired cases out.

Crossed my mind as well. Empty cases are a bit of a pain to remove from the box.

Know I have seen it else where Though I feel this is worth repeating. Start lower than your usual charge & work up with the new brass. My experience suggest backing off 2 grains may be a minimum consideration for a starting load.

I'll second that - when I switched from starline to Alpha in my 6.5CM, I ended up around 1.5 grains lower for the same velocity holding everything else equal (bullet and same lots powder and primers).

If your adventurous, make one at a grain less than your normal charge and it will tell you roughly how much more you need to go down.
