None of these companies, including Hornady are focusing on lower demand calibers (it's business apparently). Unless you shoot the latest popular calibers (6.5 bore seems to be the rage now for example, good luck). Sierra simply is not making even 30 cal stuff in their Game Changer style, not to mention "boutique" calibers like the 200gr 375. Loaded ammo as well.
Try and find 22 Hornet. I emailed Hornady and they replied, it will be available mid November and they have "no plans" to restart the 450NE or the 405 Winchester for example. I fully understand, but I'm not buying "we are busy working ten shifts etc), they are focusing on what sells. That's reality.

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…”
