22rf has close to twice the BC of the common slugs, 3 times the BC of heavy pellets, and most people can't out guess the wind past a certain distance like by 50Y to compete with 22rf.
Some brands of 22 and 25 caliber slugs are exceeding 22rf now and show a lot of promise.
Probably best to compare pcp's to 22rf at cost and quality levels. High level and tuned pcp will often out perform a less expensive 22rf using less expensive ammo and the inverse is true as well.
If you are using good pellets or slugs in your pcp's that you've found to be precise then you should also use good rimfire ammo that is also found to be precise in 22rf for a fair comparison.
This test is a good read.
