Brass stamp

[NC/Br Shooter]

I got some brass mixed up. Just primers that are mixed up. I got cci br4 mixed in with federal 205 match.
On the br4, aren't they stamped with a B?

If I remember correctly the federals should have a color on the priming anvil. You can shine a flashlight down into the case and normally see. If I remember, the federal is purple or red

The Br4 that I have are marked B on the primer cup. In your pic I can see the B stamped onto the cup.

My BR-2's all have a "B" on them yes
So Im sure the BR-4's do also, as shown in your pic

Thanks yall,

Now I wonder if load this box and shoot them , if ita throw my groups off. I aint ever done this on purpose. I went from br4 to federal 6 months ago. Come to think about it. I had to retune that gun 3 months ago. This might had been why. I thought it was throat erosion.
Could had both..
Lesson learned.

Yes changing a primer alone can vastly change things either for the better or for the worse
here is a picture showing group size difference with only a primer change

You could charge the cases with the br4 with your old load and see how it shoots.
