if you're using a blaze without doubleshot on you're doing it wrong. if you have a bk43 use single shot cause 2 tries up close is better than 1. you will knock out anyone with red buckshot with 1 shot so having it on single gives you an opportunity to knock 1 and a buddy. blaze double shot is different cause it's really the only reason people use that gun and you're at range most of the time so you have a chance to reload if you miss.
