Wise choice . probably one of the best PCP made .
Remember to clean the barrel with a pull through first then lead it with about 4 mags worth of pellets .
Pellet to try
AA express /jsb express same pellet 7.9gr
AA field 4.51 / 4.52 8.44 gr
JSB Heavies 4.52 10.3 gr
Test your gun with a chronograph using JSB Heavies ,these tend to give the highest reading in most guns ,around about 712-717 fps , better than bis mags
Mine is not pellet fussy at all but i use AA Express 7.9gr , one very good pellet doing 805-807 fps
