When the barrel lenght is increased the pressure difference between the air reservoir and the end of the barrel is the same. U do loose some pressure bc of friction allong the inside of the barrel, but this is really small.

HOpefully not bringing up an old topic but it seems rather recent. If you the detent the other way around you will most probable produce a backspin like shown here

producing a backspin in BBMG's seem's like a fundamental of these types of guns because they seem to curve alot after the bb exits the barrels (depends on what grams you use). Any opinions? i've read through it but if you put the detent the way in the diagram it will produce a forward spin which will make the projectile drop. I'm nto sure but it seems right... any objections at this point, I'm probably wrong though but its what i'm thinking.
