Chrony results 45acp, 40s&w and 9mm

Finally got to get out ot the office and shoot some. Here are the results.

All velocites are instrumental at 12 feet,
Can't adjust to Muzzle due to unknown Ballistic Coefficients

9mm Beretta 4.9 inch barrel
92 Brigadier Velocity Energy SD.
115 JHP 4.7gr Bullseye 1192 363 9.2
147 JHP Win Factory 1020 339 3.65

45 Kimber Custom Royal - 5 inch barrel
185 JHP Rem Factory 1020 428 7.12
200 JHP Blazier Factory 1014 456 17.53

180 XTP Reloads 6.0AA#5 826 273 11.53
180 XTP Reloads 6.35AA#5 893 319 8.17


Any thoughts?

165 gr bullet seems ballistically more efficient than 180 in 40S&W, 200 gr in 45 acp. This is base on energy results not accuracy.

For most loads I clocked ten or more rounds. Just FYI, my benchrest rifle from years ago (6ppc) would run 3000fps with a standard deviation of 2 or 3 fps. That represents the best I've ever seen.
