Update to my previous post, i have been out this evening with my Hatsan Stryker .25
i got x2 tree rats at 20 and 17 yds, i can confirm they do not like .25 pellets
the 1st tree rat was in the fork of a tree about 25 -30 ft high, he tried to freeze but i had already spotted him the pellet hit the grey in the head the impact knocked him clean out the tree stone dead ,the second grey was halfway up a tree trunk so i clicked at him he stopped to look silly squirrel the .25 caught him in the chest the impact again knocking it straight to the ground, these .25 pellets sure do a lot of trauma damage and i think with practise out to 30 yds should not be a problem,great calibre and the gun is great value for the money,
