Title: I don?t have a chronograph. Can anyone help?
Post by: Mustang Jon on January 25 2022 09:37:45 AM MST
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
