Go look at the Lapua casing and go look at the Hornady casing - and go look at the what 4? postings now of Kabooms, that keep involving Lapua brass. Just because yours isn't kabooming in your premium barrels with your expert practices, doesn't mean this isn't as obvious as the sun on one's face; that the Lapua and the Kabooms that go to Lapua, isn't relatied to the obvious Lapua decision to run a thin web down the explody-part of the brass at the case head, and so - Kaboom. OP's Kaboom, would not have happened if he was running Hornady brass - the picture makes that strikingly obvious. Why is this so hard?
All other things equal, the strength of a metal is directly proportional to its overall weight or size. This is fundamental to all metal deformation, temporary or permanent. The more metal there is, the more force required to deform it. Again all other things equal.
So unequivocally the thicker Hornady base is going to be harder to deform than the thinner walled Lapua. Also the more curved transition from base to sidewall makes it stronger.
