Very happy with my Discovery .22 PCP.....being this was my first PCP and I read on forums a great deal before buying.... decided to buy a MAC 1 tuned Discovery with pump as i learned the "stock" guns varied in performance...TIM's tune cleaned up the trigger,and the added power adjuster gave me 25 consistant shots I can count on ...It shoots very accurate with JSB/AA's and on my chrony it tested at 905 FPS average for ist 10 shot string and 889 FPS average for 2nd string of 10 shots using JSB 14.3 gr domes..
This exceeded my expectations and perfect for me as I only use it to hunt...I have shot on a target at 70 yards in varible wind and managed a 3 shot group of 1 1/4" after adjusting for the wind...it is zeroed at 20 yards which gives me an OPBZ of 47 yards and a holdover of 3 mil dots at 70 yards...
I have not fit a shroud as the stock muzzle brake stabilizes the barrel...so I'm living with the noise for the time being as I feel acurracy is more important....
Great rifle for the money and MAC 1 tune was a bargin..
