Yeah I'm the same way TN. But with my 460, sometimes I get sticky cases, sometimes I don't. I think the weaker brass is usually when the problem shows up (Brass that has been fired several times). I actually had the brass casing separate from the base a few times on the last trip out to the range. It separated about 3/8" up from the base. It came out just fine, but had to push a cleaning brush through from the muzzle to get the rest of the casing out. I literally had two pieces as it completely separated from the wall of the casing. Every one of them that broke, broke at the same spot. My resizing die doesn't go all the way to the bottom of the case, and it broke right at the "line" where the resizing die stops.

In my case, I really don't think it was over pressure, but rather weak brass. I called another guy on this forum that I trust completely, and asked his opinion, and he thought the same thing. I don't get flattened primers at all with the load I'm shooting, but with weak brass, it did blow apart a few cases.

Oh, and just for grins, the impact of the bullet was still online, but hit about a foot and a half low because of the loss of pressure when the case blew out. In a revolver, it would have been a much different scenario I think.

The load I'm using is well below the max listed on Hodgdon's site.
