IPSC with Delta Elite
Shot mine for years in competition. Went to Glock 20 for high capacity but shot the Delta faster, with greater accuracy. 10mm shooters get all their brass back. No one else wants it. When reloading the 10 for IPSC you load DOWN to major...to .40 S&W velocity, in order to minimize recoil yet score well. One could use a good after market .40 cal. barrel to make use of cheaper brass but 10mm brass is so strong that you get nearly unlimited loading when down loaded to .40 velocity. It is not that different than shooting any other major caliber 1911. Do not hesitate. Competition is a blast!
