Welcome to the nuthouse.

The HW100 is a heavy bit of kit, but very nice I would admit. The best bit of advice I can give is to go along to your local rifle club or shop and try a few different rifles out for yourself, and see which you like the best. The local club will have loads of memebers who will be more than willing to let you try their rifles.

Have you had a look at the AA410, Falcon Prairie, Daystate, etc etc etc. So many to choose from and so little time

P.S. The new fangled PCP thingys need a charging system, so don't forget to allow for a decent pump or bottle in the buying price.
