700 mm HEAVY LINER tested in the FX Impact M3

This is a review of the 700 mm superior heavy liner in 177 for the FX Impact M3.
3 different slugs are tested at 100 m:
13 gr Zan
15 gr NSA
16 gr Zan
I am comparing the 700 mm heavy liner to the 600 mm heavy liner and the standard superior liners in 600 and 700 mm.
In the video I say that the best group I shot in a previous test of the 15 gr NSA is a 4,4 cm group. This is incorrect. It was a 3,7 cm group and it was shot in the first attempt.
Enjoy
Best regards
