House Rule - Stray Shots

The 41st millenium is a brutal and unforgiving place, as such if a player shoots while in or into melee combat and misses his target by a small margin (one degree of failure or less), the attack instead hits another target engaged in the same melee. If there are no other targets, the firer cannot hit himself.  
If anyone shooting into melee combat with a Semi-Auto Burst or Full Auto Burst must allocate multiple hits to different targets engaged in the melee equally between all targets.
