The most accurate pcp I have owned would be the fac single shot BSA hornet. My, this rifle can put 1/2 inch groups at 50 yards in .177. My only regret is that I sold it to finance a 6 mm Dennis Quackenbush single shot shooting 55 grain pellets from the pellet man. 130 ft lbs of energy from this rifle. 25 shots with one fill. Big bore Bob worked this rifle over after purchasing from Quackenbush. Still waiting for delivery of the new
rifle.
