The chart does not include the 41s. Any idea on how they measure up?
Is hardness of the brass necessarily comparable between brands?
CCI-41's have the same cup thickness as 450's & BR4's; can't say about the relative hardness between brands, but I would suspect that it's very similar absent any other data.
There has also be a few reports on pierced primers in the newer WIn SR primers as well.
There's just no reason the use the thin primers in an AR, unless that's absolutely all that is available.
I use CCI-400's, Fed's & Win's w/o a 2nd thought in bolt guns.
