A friend of mine just bought a 240 cobra and we have not been able to find any load data for it. If anyone here has any info. on this caliber it would be greatly appriciated.

If you start with .220 Swift loads you should be alright to start. This is correct in most instances of simply necking up a cartridge to a larger bore size. The Cobra is in the performance neighborhood of a 6x250.

"Wildcat Cartridges vol2 " Wolfe Publishing has a few articles on 240 Cobra.
Quickload http://www.neconos.com/details3.htm will give you a starting point for load data.

as with any caliber, you cant go wrong with starting at 90% case capacity and go from there.

Oh, yes, you certainly can go wrong!!!!!!!!!

Beware, any who read this: If you follow this "Rule of thumb" with a powder that is even moderately too fast for the cartridge, you WILL create dangerous or even catastrophic pressure levels!
