This is getting to be a pretty crowded space. I can recall when there was nothing but limited supply of old Kynoch 404 jeffrey and the distant memory of the 416 Rigby. Both back strong today. Now we also have the 416 Remington and 416 Ruger. Another recent wannbe 400 H&H and the not much heard from lately, the 416 Dakota. Hornady is even loading the 450/400 for a rimmed option.

Now a 10.3 x68. I think a serious lack of imagination, if you ask me.
