On the lower cost end, generally as FPE goes up into the Magnum range, accuracy goes down (in many cases due to the shooter more than the rifle).
Most people feel it is less of a challenge to achieve good accuracy with lower powered air rifles.
My 22 Cal Benjamin Trail NP2 (magnum range 20 FPE springer) will print groups which are sub-nickel size at 25 yards.
Many of the lower powered springers will literally stack one pellet on top of another at 25 yards. Here is a picture of a 25 yard group with H&N Field Target Trophy 14.66 grain 22 Cal pellets with the Benjamin Trail NP2
http://postimg.org/image/jee59qtaz/ I have a half dozen springers and it may not be accurate to say "many" springers stack pellets at 75 feet? And my springers span from $150 to $750. I would not want someone to spend $200 and think they could "stack" pellets at 25 yards. One of my FWB300s or my AA TX200 mark3 shoot pretty well. And so do some of the others with the work I've done on them................. but if you go out and buy a springer don't be disappointed if they take some work and a lot of practice to do what you will read on the net.
