Thanks alot lads.
In reply to your questions, it was sent directly to BSA but they just sent me a brand new gun with the same problems.
I tryed a few different pellets, accupell, RWS superdomes, Milbro etc but it didnt up the power very much. And i can see what your saying that 10.1FTLB is enough to kill the rabbits but I see it like if i bought a brand new car and was told it can do 100MPH but it only does 70MPH, 70MPH is quick enough but i paid for a 100MPH motor, if you see what i mean.
Thanks again, very helpful
