Hey Ho Jax Orebetter!
What a can o' worms. I am first to admit that I am not too keem on such rools, but what you jest described seems to be a 10 degress rool, not a 170 degree rool. Let me get myself in trouble by explaining my understanding and then you and others can try to edgekate me.
Under SASS rules, the shooter gets 170 degrees of firearm barrel pointing travel in any plane of movement given that straight down range is the 90 degrees reference and moving the barrel in any direction adds degrees to the 90. So what ya really get is 85 (half of 170) degrees freedom of pointing in any direction from straight down range. So, if you point straight out to either side, that would be 90 degrees and yer in violoation by 5 degrees. Same if you point straight up and in theory straight down, but like you said it would be near impossible to draw or reholster if straight down were enforced strictly.
Clear as mud? I thought so. :roll:
