I've only been shooting air rifles for about a year and half and own four springers, two FWB 300's, a RWS 34 in .177 and a Diana 48 in .22. The challenge of shooting them well was what drew me to them, well the 34 and 48 anyway, a monkey could shoot a 300. I'm blessed to live in a rural area and have a 100 yard range in my back yard that I shoot everything from my air rifles to my center fire rifles. I have a bench set up behind my shop and I can shoot out to 500 yards there.
So far a PCP has no appeal to me for the same reasons as others have mentioned and for the cost of a good one I can buy a very nice .22 rimfire target rifle and stretch it out to 200 yards for a challenge.
My first rifle was the 48 and it was a steep learning curve to learn to shoot well. The 34 followed and I love it, my go to fun rifle. I wanted something more accurate so I bought the first 300S and it's amazing. Then I thought if I had another 300 I could shoot one with a scope and one with factory peeps so I bought another. I was all set I had rifles to cover everything I wanted, or so I thought. Now I'm considering finding a LH 601-603, it really is a sickness.
I won't say I'll never own a PCP but something in my reasoning is going to have to change before I consider one.
