I am looking for some advice. Going to be looking fro a decent starter pcp rifle. Mainly going to be using it for some friendly target shooting primarily. Currently looking at a second has s200 or s400. Is there much between them or is it down to looks and feel? Are there any other used rifles around the £4-500 mark that are also worth a look at that I may be missing? Is .22 going to make a difference for recreational target shooting or should I stick to .177 to get the feel?

Thanks for any incites you may have.
