Research notes
Many 50-caliber competitors consider the case volume of the original BMG cartridge to be more than adequate for 1000 yard shooting and they seek improvements in the form of more precision rather than added velocity. Taking a page from the small caliber bench rest bible, they are turning to shorter cases in their search for an increase in accuracy. There are numerous examples but all are based on the 50 BMG case and most share the common traits of reduced body taper and sharper shoulder angles. (IAA Forum)
