I used to use TM BBs exclusively, but I have since switched to 0.28 BB Bastards and they've been great! Although I find it odd that I found 2 deformed BBs in my first package - image below. But to their credit, I haven't found any others in subsequent packages, and TM is not faultless for deformed BBs either - it was just odd.
Does anyone know how pervasive deformed BBs are in general?
