you wont go wrong with one
I like mine that much I bought another
very accurate once you find the pellets it likes put a good scope on it and it will hit what you aim at
your hw 100 take it to the airgun doctor in Cannock .mine leaked to empty overnight it was fully serviced and a problem found --sorted fixed and done while I waited -never had a problem in 2 yrs ---don't remove the air bottle its the most common cause of leaks
