since ive been using .177 i havent seen a rat, but i bet there would be no matrix style pellet dodging going down in my scope! as for .25, i dont think i will ever get one. never know tho.
and yes pcps have a place, but i think i see them more as a tool for a job, whereas a springer is a lot more of a personal affair.. to be enjoyed more and to be mastered, conquered.
