The two are defined differently to distinguish between the effects of deterministic errors ( range errors, average wind speed errors, aiming errors etc.) and non deterministic errors (pellet yaw, muzzle velocity error, wind variability etc.), the latter largly determining group size and the former determining accuracy.
For hunting you need a combination of accuracy and small dispersion to produce precision and a high degree of first round effectiveness. A 5p group of 10 pellets around the aimpoint, fired under all conditions at 30 yards, or any other unknown range, is perfectly acceptable if it can be repeated on three different occasions under different atmospheric conditions.
Would you mind filling in my tax returns please . as if you cannot baffle em , nobody can . well done that man ??? HOLLY

PS what we need in air gun articles , is what nick jenkinson used to do . show us real world groups at various ranges , out doors . benched . say 25 , 35 . 45 and 55 yards . with the best pellets the reviewer can find in that rifle . not acceptable accuracy . or very good . seeing is believing .
