A couple of thoughts. People that buy doubles, usually don't quibble with pesky issues like costs of ammo and in my observation, tend to buy it by the case. As far as solids is concerned, there is still plenty of non-US elephant hunters out there, not to mention the thought it's probably safe to assume Trump will drain the Swamp at USFWS and we'll be back to normal again. Further, there is still a use for solids. Hippo on dry land comes to mind, as well as White Rhino which can still be imported, not to mention the fact many PHs still carry solids as their daily carry. Lastly, the fact the solids are on sale is a good indicator as to the reason why.

I hand load for my 450NE, and even I'm shooting cup and core Hornadys, rounds are still pricey.

A good principle to guide me through life: “This is all I have come to expect, standard lackluster performance. Trust nothing, believe no one and realize it will only get worse…”
