Certain revolving rifles(and shotgun, in the case of the MTs-255) have ways of either deflecting or disallowing the spray of gas and excess powder.
If you can just open your slanted eyes for one moment, observe the shield forward of the cylinder here - >>582194 - that leaves no gap and instead causes gas to harmlessly spray into the rear of the forestock.
The Taurus line of revolving rifles, one of such pictured here, has a more crude method in place that deflects gasses upwards and into the air. Though not perfect and sometimes sprinkles your arm with powder, it keeps the level of discomfort down.
There, you've been schooled on how fucking retarded you can be.
