Saw one yesterday in a gun shop
Called a beeman 2016 db (not to be confused with the beeman with interchange barrals)
One barral in .177 the other in .22
Uses one piston to fire both barrals which are fired at the same time so you can fire
.177
.22
Both
Does anyone have one and what use is a rifle firing 2 pellets with difrance of trajectorys and speed.I can't even see the point if they were the same cal. Does dry firing do the gun anygood
Anyone got one or has anyone shot one
