My old Hornady manual says the .240 Weatherby is "nearly identical" in capacity to the '06 case. There is a fellow at my shooting club who has dies for swaging 30-06 brass into .240. The belt and head are the same as 30-06, body size is slightly smaller - the swaging dies squeeze the body down and swage on a belt as nice as you please, though it takes a hydraulic press to do it! (Not even a Rock Chucker is tough enough <!--emo&--><img src="http://beartoothbullets.com/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=''><!--endemo--> , or we're not strong enough! )
The point of all this is, the .240 is slightly smaller than 6mm-06, so you should be able to use .240 data as a jumping off point. Hope this helps some. IDShooter
