JimH,
Do the 25's kill more better than the 22's in your experience?
Never had a .22 air rifle,but the .25 smacks squirrel's noticeably harder than a .22 short,plus they are quieter,more accurate and safer,as the pellet slows down sooner .My marauder shoots a 25-26 grain pellet 850 fps.Sight in at 35 yards and down 1.5"@ 50. Easily shoot 1/2" or better @ 50 yards on a calm day.I own several nice .22 sporters and target rifles and the marauder is the most fun rifle I own.
