This load produced some stout recoil but nothing uncomfortable.
I think the drawing is about right on dimensionally. Case length of 2.4", OAL of 3".

Some day I will have a .500 3" too. On a large '02 Webley to boot. Should be a wonderful gun.

IMO, the 50-110 in a Ruger is a great gap fill between the mediums and the big NE chamberings and can be built up as a lighter package as well.
