Aaron, thats about 23 pellets a day
I tend to put a 500 to 750+ per week when plinking (the advantage of being on sick I suppose) sometimes more!
Now if your gun's only doing 8ft/lbs and you think its down to the amount your firing buggering up the spring, I would suggest you go out and buy a cheap Chinese gun as mine has had many thousands of rounds down it and is still doing around 10.5 to 11ft/lbs

Getting a cheap gun is more fun aswell if you have iron sights
