Finally loaded up the 124 gr Nukes. I tested the loads in the following pistols:

Gen 4 Glock 26
Gen 4 Glock 19
Gen 5 Glock 45
Sig P226 Navy

due to the various chambers, loads were loaded to an OAL of 1.060″. Brass used was mixed. Primer used was Federal SP mag. Powder was Silhouette.

Powder charges:
5.5 gr
5,7 gr
6.0 gr

Velocity ranges for each pistol:

G26 1109-1176 fps
G19 1148-1222 fps
G45 1114-1187 fps
P226 1129-1189 fps

Best loads are the 5.7 and 6.0, but still need to do further accuracy testing
