[QUOTE="KY Gun Geek, post: 288051, member: 13807"] Dug up my targets and chrono data - ran it all through Loadbase. Very surprising! Input data listed below, but the net is to get the drop numbers to match, I had to back the BC all the way down to 0.33. The advertised BC is 0.43. I will do more verification of this (including down range velocity measurements). Anyone else seeing this? Here's my input data. Please verify if you have software (to make sure I'm running it right): MV 2890 (measured with chrono) Drop @ 300yds: 10.75" ZH: 0.8" (measured from 100yd target) Bullet Weight: 225gn If you care, atmospheric numbers: Station Pressure: 28.78 Temp: 66 RH 44% [/QUOTE]
