OK, I mean how many times has your favorite firearm changed? I have had many guns that really were my favorite at the time but time usually changes the list. Its the same with calibers. Many times I have tried a new caliber and it instantly became my new favorite. I quess guys like me are good for the industry. I quess I will always have a 270 and a 6.5x55. I can't recall not having a 45-70 or a 45 ACP. Most other calibers have come and gone.
