Hi Rob mate how's your F1 doing? Mine's still going strong.
I have had a go with a few HW springers down the club and they are fun to shoot, the best though was a 95 and it had been "tuned" (this is not to up the power, in case anyone thinks it is so, rather it makes the action smoother so it is smoother/quieter). Really good fun for target shooting but also useful for small game (rabbits etc).
That said I splashed out on a HW100 on the grounds I was going to be using it for pest control on my permission and the 80+ shot rate on a single fill plus the 14 pellet magazines that make downtime between shots minimal and quiet so as not to scare off the quarry. The PCP type rifles are also very quiet and have virtually zero kick which improves accuracy, but that will never make anyone a one shot one kill hunter or a bullseye target shooter every shot taken due to sudden changes in wind speed or a slightly deformed pellet or a flipping leaf stalk getting in the way suddenly.
Whatever rifle you go for find the pellet that seems to work best with the barrel and learn the rifle, each even in the same stable will behave a bit different. Most of all enjoy it, it is fun.
Rob.
