Mmmmh, dude, did you tested damage IG? Because at range only 1/3 of bullets can hit main target, rounded up. And with 8 bullet, I actually think 4 can hit the target, or it would mean the spread isn't symetric (or that a bullet disappear, unlikely).
If you want to make enemies, try to change something.
XL70 would have 3.66 bullets hit the target on average, AR would have 3.75.
