Hi guys. many thanks for the guide,
I have tried many times and find out some date for mod,
Range: C8 43=400 ,Fa 43=500, 16 44=600, Fa 44=2000, 48 45=3200, 7A 45=4000
melee:20 41=10, 48 41=12.5, 70 41=15, A0 41=20, C8 41=25. F0 41=30, 20 42=40, 48 42=50, 70 42= 60, 8c 42=70, 96 42=75, AA 42=85, C8 42=100 same with damage
rate: F0 42=25, C8 42=30, 96 42= 40, 70 42=50, F0 41=100, A0 41=150, 40 41=250
Accurary: CD CC CC 3D=10, 00 00 80 3E=25, 9A 99 99 3E=30, CD CC CC 3E=40, 00 00 00 3F=50, 9A 99 19 3F=60, 33 33 33 3F=70, 00 00 40 3F=75, 9A 99 59 3F=85, 66 66 66 3F=90, 00 00 80 3F=100
and the 4 number behind the accurary can be understood as ballistic or damage decline, all the smoothbore are 66 66 06 3F, strong on short range and rifle gun use: 66 66 26 40, strong on long range. and most rifle use CD CC 8C 3F
