After using them on both of the default shotties for around 50 kills each, I can easily say that they disappoint. Standard buckshot will almost always kill in 1 or 2 hits out to medium range using my setup, but these things take atleast 2 shots in close quarters, easily 3 or more a bit ****her, and unlike buckshot, they disappear at range. I can VERY occasionally get a 1hko with them, but that is very rare. The DoT is very short as well, only like 2 seconds, and rarely kills the enemy. I am a shotgun only engineer, and this disappoints me, considering the fire they leave is so cool. Any other thoughts? Also, I just unlocked the m1014 and mts 255, how are they in MP?
