[QUOTE="Trickymissfit, post: 531189, member: 25383"] probably be a fine cartridge, but case supply is pretty hard to come by. Add to this the double radius shoulders at about 45 degrees, and case forming is really going to tax a press. I wonder what the actuall case capacity of the .240 WBY would be compaired to a 2.45" 30-06 case with a 30 degree shoulder and .010" total taper in the the body. The closest case I can think of would be the 35 remington, and it's already a half inch too short. The idea kinda falls right in there with a case I've been designing off and on that uses generic 30-06 brass shortened to 2.375", and has a 30 degree shoulder with .015" taper in the body. The idea is to make the loaded round fit into the magazine with the longer bullets, while still being fair close to the lands. I think the round is good for 2800 fps with 140 grain bullets, and may well reach 2900 fps with something like H450 in it. gary [/QUOTE]
