twodownzero Posted March 8, 2010 Share Posted March 8, 2010 (edited) Hi guys. I rarely get the chance to chrono (it's actually been over a year since I chronoed any pistol loads) and so I figured I'd share my results for those of you who have a hard time hitting the outdoor range on a nice day to chrono. There's also a load using S&S Casting's 147 grain cast bullets and my carry load with Gold Dots. This is cut/pasted from Excel. Power factor is calculated using the INT function, which drops any decimals (just like in real life, 124.9999999 is not 125 and thus not minor, etc.). Standard deviations are rounded to 2 decimal places, velocity to a whole number.
