I believe we castboolits types think there is more demand than in reality there is at times. I actually fell into that trap when complaining they had 475L in stock and no 480R despite it being the slightly more popular cartridge (Remember: about the only 475L guns are custom plus a few BFRs, etc). Then I learned the last 475L production run was from before the pandemic.
For example everyone here wants or has a lubrisizer. Wouldn't it be interesting to know if for example this forum owns 30% of all that have ever been made? Now that may or may not be true but you have to think like that sometimes. Not saying that this forum possesses most of the Dillon progressive presses or purchases a large percentage of Nosler bullets but we may be buying more molds or 480 Rugers on a percentage basis than we realize.
