I just went for a 2nd hand PCP after "some" years of knocking magpies over with a £30 mail order .177 baikal with a £10 scope! (yes it was a while ago when I got it!)
it was the reduced noise and the extended range I got it for. (baikal was only useful up to about 25yds if I am honest and sounded like a car door slamming)
I got a second hand Falcon FN19 with all the kit, pump, pellets, AirArms moderator, targets, 3-10x44 IR scope and slip for £350.
It is really simple to strip (essential IMO)
very quiet (more so now with some tweaks)
shorter barrel than some(required)
much lighter
