    I went and got some powder and primers today. They had the CCIs all stacked together and I grabbed the wrong primers.

    I usually use the #400 SRP for .223 in my AR but I grabbed the BR-4 SRP by mistake.(bench rest primers) So is there really any difference between the two other than price? I don't really want to work up new loads to use only 1k primers.

    The issue is not the load. Rather, it's the strength of the primer cup. If you're willing to risk a blown primer, or a blown out primer rattling around in your rifle, you don't have a problem. In all likelihood, you won't have a problem on any account.

    So I take it the primer cup is thinner or softer on the BR to increase reliability?

    I am not running max loads. I can use the BR4 for plinking fmj loads or cast boolit loads.

    My understanding from the same question I asked CCI/Omark was the primers were compound weight consistent,cups were same hardness as standard primers with the exception of BR marking. SJ 40

    You grabbed a higher quality , more consistent box of primers . Save them for a lower quantity of more precision loads if you load for accuracy and consistent groups . IMHO while primers do have a say in overall accuracy , I have not found it to be too significant .

    Ok so the BR are thicker, the opposite of what I thought. Thanks for the info everyone.
