Is the .450 Howell pretty much the same as the .450 Guns & Ammo? I can't find the G&A round in my Cartridges of the World to compare. I did pick up an old tang safety Ruger M77 in .458 WM back in October to go with my No. 1 .458 WM. The loading in that M77 magazine has to be 3.340", no extra room.
There is a 460 G&A which is a full length Improved 404 Jeffery necked up, so like the 458 RUM. There was also a short one and that would be like the 450 Howell.
