not sure if the answer is yes or no but you are walking a fine line, if a stage calls for 10 rifle 15 pistol and 6 shotgun and you shoot 10-28 and 6 you could get a “spirit of the game” infraction occurs when a competitor willfully or intentionally disregards the stage instructions in order to obtain a competitive advantage, you would get the time of the extra rounds fired, possibly assessed a Procedurals are unintentional “mistakes” where the competitor engages the stage in a manner other than the way it is supposed to be shot. Procedurals are scored as ten-second additions to the competitor’s raw time for the stage, no more than one per stage, firing into a berm has some hazards also, if the round goes over the berm it is a match DQ, if you hit a target you get a P for shooting out of sequence, or you could get 3 misses due to expended rounds not hitting a target. Best thing to do drop mag eject chambered round.
