[QUOTE="J E Custom, post: 398185, member: 2736"] I am interested in the performance of the 50 (.510) BMG after it goes Sub Sonic. I know that most bullets really lose there accuracy when this happens and was wondering if anyone had done any comparisons between lighter bullets and heavy bullets at sub sonic velocities. Question: Are the heaver bullets less effected by the transition to sub sonic or they essentially the same. The old Black powder rifles are capable of outstanding accuracy at long distance and most go sub sonic soon after they leave the bore. They usually use 500 to 600 grain bullets and the modern LR rifles use 250 to 400gr bullets at much higher velocities and with much better BCs. With the better 50 cal bullets(BCs over 1) and muzzle velocities over 2800 ft/sec they go through the transition at well over 2000 yards with 750 to 800 grain bullets. So I was wondering if heavy projectiles were less effected during Sub Sonic flight. All opinions are welcome but also anyone with facts and figures are what I need . J E CUSTOM [/QUOTE]
