I wrote Berger to find out any new information on availability and twist. Eric Stecker wrote back ( in less than 10 minutes I might add ) : "We have a lot of work to do before the 338 cal bullets are completed. I estimate that this will be completed in the summer of 2009. Understand that I also estimated we would be done by Sept. 08. All the 338 cal bullets were designed to work in a 10” twist. Once the bullets are physically made we will know for sure but for now a 10” is my best recommendation." I guess there is no need to sit on the edge of my chair waiting edge.
