Well so much for brand new BSA mk2 .....

100% agree with you Ken. I put a 16x Centerpoint on mine (decent scope for the price I paid) but this rifle deserves an optics upgrade. I did a little more tweaking to the tune and have it shooting the 15.89 JSB's at average 876fps for 50 shots with an extreme spread of 15. ES of 13 if I take out the low shot of 868 in the middle of the string (bad pellet? - all taken straight from the tin). This is with the factory regulator. It will put all of those pellets on a quarter @ 50yds. It can do 10 shot nickle size groups on a calm day. So happy I bought this rifle.
