Amax and vmax rounds have an excellent reputation. I've heard 50/50 on the brass, some people complain about loose pockets but I haven't see. It. I wonder if it is a manufacturing consistency QC issue or a certain primer or load issue which is why I've been asking for the details. I have yet to have a primer fall out of any brass. I've only had one case show pressure signs on the back face where the ejector left a dimple and that Cass seperated on me. So I'm going to pull my die up a Tad and get new brass. 42.5 gr is the Max I plan to load now.
