Exposed Hopper
Although we all think it is obvious, I have found that every time I used to snap shoot on the speedball field my barrel was against the bunker but the hopper was exposed and out in the open. It seems dumb but subconsciously it happens without you noticing and the next thing you know , your in the dead-zone with a splat mark on your hopper , so I just make sure my hopper isn't sticking out and I got a new smaller feedneck so my hopper is more low profile.
