[QUOTE="tim_w, post: 1451064, member: 11132"] Actually when you consider its lossing very little vel compared to supersonic flught there would not be a huge increase in drop rate compared to the same bullet supersonic. I know its a way high because compared to the 45/70 basically wadcutters, but the ratio would be close to the same. consider according to jbm traj cal it takes a 220 SMK 1500 yd to slow a mere 300 fps from a 1000 fps mv. What is that a loss average of 20-25fps/100yds? Looking at the chart vel as well as traj drop rate stays fairly consistent from zero to 1500; in the 20s moa rate.. The decay rate is just so minute comparitively becuase vel loss rate is so small. Its i weird looking at subsonic drops aftter years of long range drops working with supersonic only performance. Can you imagine your 300 BO rifle angle to hold for 309 MOA@1500 LOL. THats 4859” of drop with a 100 yd zero. Wow talk about lobbing one in there!!! [/QUOTE]
