On a different point, I've heard shotguns being complained about before too. Depending on the ammo weight, proximity, shotty type and how it's being fueled/upgraded. TM style gas shotty upgraded to fire x6 shot at 350fps on 0.2g hurts enough when they are close enough for all the bbs to be on target. Stick 0.3 or more that I have heard of people running it with. That's close to 2g of bbs hitting you in a concentrated area. Up that there's the aps not as powerful but takes a bigger load, even on 0.2 is a fair whack. Far worse impact than a short 3-4 rnd burst.
