Posted this in another thread, but putting it here as it is charting:
Instead of buying NEW gear, if you want to have similar results to .50 caliber with a .68 caliber ball: I.E., have it hit with less force and not scare off the kiddies an even better method is dropping the FPS on the .68 for indoor play. No new gear, no added expenses.
at 225 FPS, a 68 caliber ball has very similar ballistics as a 1.25 gram .50 caliber ball traveling at 300 FPS. They go the same distance, they will break at the same distance (roughly 90 feet if you don't lob them), and they have a similar energy impact (FPE).
Link to data:
(FPS over Distance)
(FPE - Energy over Distance)
So why change out all our gear, all our hoppers, everything, when we can just use our existing guns and gear to achieve a similar result.
AND an extra bonus will be the balls are moving slower and will not scare off the new players. To make a .50 caliber perform similar, we would have to increase the velocity, thereby having a faster traveling ball, more safety issues (PSP already needs new netting for the .50 cal ball, nevermind at higher velocities), and you'll be scaring off the kids for sure shooting that fast.
That answer seems a no-brainer to me. Drop the velocity of the .68 to 225 for new rental players, and achieve the same result as what .50 caliber is promising us.
