RE: to crimp, or not to crimp
Target shooters demand the most accuracy that they can get.Having the most uniform pressure aids accuracy so if crimping actually did make the pressures more uniform target shooters would crimp.To quote from the second edition of sierra bullets reloading manual page 35-" Crimping generally reduces the accuracy of your loads because it adds another variable to the reloading process" . The factories crimp ammo to prevent bullets from moving in the case due to extremely rough handling which only happens in tubular magazines or when when people abuse their ammo.Also the factories use cannelured bullets almost exclusively.Even some of the bullets that have no cannelures when sold as components have cannelures in factory loads.
