Hmmm...thanks. That hadn't occurred to me.

I would check the rounds in question, could be they are slipping past the shoulder in the chamber causing a headspace issue. Might be an oversize chamber as well, that could cause the same issue. It can be a very fine balance for a manufacturer, make a chamber large enough to accept everything on the market, but not so large as the rounds held to a tighter tolerance don't slip past the shoulder. Can be a big problem for rounds that headspace on the rim.
