H&N 177 Slugs Review

This is a review of the new 177 slugs from H&N.
I am testing the slugs in 13 and 16 gr on 34m, 75m, and 100 m.

The settings of the Impact is 134 bar on the reg.

What I did not make perfectly clear in the video is that the groups shot on 75 and 100 m are the best of MANY attempts. The other attempts were mostly not even close to the ones that I chose for the video, and that is also a reason for my verdict.

The tuning of the gun while using the H&N slugs was very challenging and while other slugs can be tuned within one single mag, these took several tries, as mentioned in the video.
A 5 cm group at 100 m might seem ok for some, but when it is the best group of 8, it is uacceptabel.
All attempts with the 16 gr at 75 and 100 m are done at 907 fps. Higher velocities proved worse as you can see in the video.
So this also explains why I will not buy them again. The slug that I will compare the 16 gr H&N to is the 15 gr NSA and it can be shot at 980-990 fps. So why chose a slug that is performing its best at 907 fps over that???
