If I were to pray for a custom caliber Diana option it would be a .20 cal D460! THAT is intriguing to me. I love my .22 460 but a 5mm version would make me sprain my elbow reaching for my wallet too quickly.
Hector,That will be very interesting to read, for obvious reasons.The 20 fpe "limit" for easy magnum accuracy / consistency has been hinted at in various places over the years. I'd like to have a little more MV and ME (just a couple ft.lbs.) with mine, but I'm very willing to be persuaded by a sound argument otherwise.
