SU - +1
Brass may not be the weak link here - as I think Steel is more likely to BLOW whereas Brass can FLOW.......
Maybe or maybe not those loads are safe....100%, but I'd hate to be holding an action that decided otherwise.
MAYBE a Ruger #1, but a fellow on the fire has had one let go also, I just think safety is first, and if one needs more speed, it can be had by rounds designed to do so.
