So I ordered a .177 die set from GMI a while back and have been testing these last weeks.
The slugs are hollow point with a flat base and I make them from 13.4 gr upto 21 gr.
Got the best results with the 16.2 gr so far.
It seems like the harder I push them, the better they perform !
Testing ground is outside in a field.
Squares are 15 x 15 mm and the 3 shots are 16 mm apart (0.63 inches). This is shot at 100 meters or about 110 yards. Not bad at all for a .177.
Velocity is 960 FPS and 33.2 FPE with STD of 3.1 FPS !
