Uragan .22 shooting the 25.39 gr redesigned

All Uragan owners know how accurate it is with the 18.13gr JSB’s
One of the most accurate guns I ever shot.

Lately, I tried shooting the 25.39gr redesigned. The maximum velocity I could get was around 850fps. Surely not enough to shoot these pellets accurately.
I tuned the reg and she is pushing them now at 930fps. I am very satisfied with results.
Here is a video comparing the Uragan with Huben K1. Both are shooting the 25.39gr redesigned.
Video is in Arabic, but with some English captions.Hope you enjoy it.
