BB Weight is all designed for the FPS out-put of your gun,
The higher your FPS, the heavier BB you are going to need in order to maintain a stable and accurate flight Path ( Trajectory ).
This subject has come up so many times itīs not funny anymore, use the SEARCH and you will find !!!
To use both ends of the spectrum, Nobody is going to be using .12īs in a gun that is shooting 650 FPS !!! same goes in the other direction .88īs in a gun shoothing 200 FPS !!!
Your FPS+BB weight+Hop-up+BB quality+Shooter Skill is what is going to affect your accuracy !
A crappy gun, with substandard BBīs that are either too heavy or too light, in the hands of a Players who has no Idea what he/she is doing is nothing more than an Easy Target.
There are plenty of BB weight tables and charts on the Net, a good source for a starting point, but based on the gun, BBīs, Skill, they should only be used for reference.
