Can someone explain to me (in simple terms) why there seems to be a never ending shortage of the most popular pellets but a monstrous supply of the less popular pellets and slugs. The supply chain issue is wearing quite thin now. It seems to me that the pellet manufactures and suppliers are wanting us to shoot what they give us rather than what we want or need. I have asked numerous suppliers but no one seems to know the answer. Some one smarter than me, please fill me in.
