Good Reply Rat, Don't shoot at a distance that you cannot hit a 10p piece at.
BSA Meteor, well was ok for clearing sparrows out from under the slates( back when they were classed as vermin), and the odd rat, but you really need something better if you wish to hunt rabbits and woodpigeon.
Like HillBill said, they are only around 8ftlb, so really only good for close stuff.
Look around for a second hand HW85 or 90, or one like SF's must be plenty out there. Stay away from the pre charged stuff until you are really sure that you want to go down that route.
Either way I am sure you will enjoy it, and as has been said, make sure you have enough for a decent scope AND DECENT MOUNTS, we are talking spring rifle here and they can move a cheap mount.
You can take the scope and mount off if you decide to upgrade the rifle so don't be scared to spend money there
Enjoy
