Don't tell me that in this big audience no one has experimented with guns having muzzle brakes i.e. determining the effect of removing or covering up the vent holes? Personally when there is rainy or snowy weather I wrap the muzzle brake and end of the muzzle with electricians tape to prevent water from getting into the barrel. The tape blows clear when the rifle is fired but it has no effect on the point of impact, at least on my rifle.
