What!!!!!7,5J????OMG that can open a hole on a wooden door !!! yes here 1J is the limit for all guns but since most sniper rifles may surpass that limit the strongest sniper i have seen could do nearly 3J (extepton if you have a Tanaka or similar sniper gas rifle were you can ajust the gas presure form min near 1J to max almost 3J ) there are rules of engagement during oficial tournaments! But for those hardcore snipers!! They often do special events or courses just for snipers. The limit there is higher and you can use even the 8mm bbs on full power(like a garand rifle or a Barrett).. For example this is a small vid from a sniper tournament, its the last of a series of tests that a sniper has to endure so he can collect points. sry but the vid quality isnt that good its a shoot the targets on the distance while you have to endure and keep your focus and calm during alot of distractions time trial
The first 3 will get for a prise some cool optics
