Can anyone help with a guesstimate the velocity? I loaded up some 200 gr coated hard cast with 3 different powders and found the 3 loads the G29 likes.
1) 7.6 gr Longshot
2) 7.6 gr Power Pistol
3) 6.3 gr Unique

Does anyone have the program that can plug in this info and get a close velocity guess?

200 gr
COL: 1.265
LPP
3.78 inch barrel

These are my estimations for the 3.78" BBL

1) 7.6 gr Longshot   1080 to 1100 fps
2) 7.6 gr Power Pistol   1080 to 1130 fps
3) 6.3 gr Unique    950 to 1000 fps
