i Shoot .177, .22, .25 and have never had any problems with either Cal, Brought up with .22 Springers and only started Using .177 Cal
about 2 yr ago, but You deffo have to hit the mark more accurately with the small cal which is only a good thing to being a better shot.
just started Using the .25 Cal and for Ultimate Kinetic energy delivery it's awesome, Wipes the floor with .22 Cal and .20 :laugh:
