when to clean barrol

[HUNTER-X]

Hi all 
I have the fx Royal 500 and it shoots like A Dream. But just the other Day when i was out 
shooting it lost accurcy. I cleaned the barrol
and pingo 2 Inc groups at 50 yards again. 
How often do i need to clean the smoot twist barrol ? I have never cleaned the barrol before now. Ca. 2000 shots sine i Got it last year.

You should start by cleaning it once a week if you shoot daily. When accuracy deteriorates cleaning it is necessary. It honestly depends on how much you shoot. The more pellets you shoot the more you have to clean it, especially if you shoot many hours of the day.

I have two FX 500's. Between them I've shot around 39,000 JSB Kings and have never cleaned either one. I can't see any loss in accuracy and never a pellet spiral. Have fun, Scott

Problem Solved  
After i went shooting again today the problem returned. This time i was sure it was NOT lac off cleaning. It turned out to be loose scope mounts . After tighten the mounts it shoots awsome again . Thanks for your replay
