After looking at the various 500 caliber options for bolt action stopping rifles, it seems like a "necked up" variant of the 465 H&H to a .505 H&H would be about perfect. They would need to blow out the case a bit so it's .560 at the shoulder, this shouldn't be a problem since it's based on the 378 Wby case and that's where the Wby case is. They could start the shoulder at 2.0" instead of 2.106", keep that nice sloping shoulder, and keep the COL to a reasonable 3.60 length. It should be a bit slower than the 505 Gibbs with significantly less recoil and fit into normal full length magnum actions. Maybe once I get used to my 375 H&H and want to step up ...

Just a thought
