Its all about profit margin and 22 rimfire is low profit margin for one.There just as much to blame, they make enough to fill orders no more.
Do you happen to own a business?
If you do, are you concerned about profit margin, and your company making money?
I doubt that they are intentionally slowing production, on an overall basis. They only have a set amount of tooling and capacity, and choose to use that to produce what is going to make them the most money. Can't blame them one bit for that.
As much as we don't like it on a personal, it's-all-about-me level, should you really expect a company to sacrifice profit to keep YOU happy, with low priced, lower end ammo?
Pretty na´ve and self-centered point of view.
