This isn't the time for the question. Whatever answer we give, collectively, how many thousands of dollars do you have?
22lr: 5,000-20,000 depending on how many 22's you have. I would think at least 5,000 per firearm.
Primary handguns: 1,000 FMJ and 500 JHP per major caliber. These are my goals for my 9mm and 45acp.
Primary rifle: 2,500-5,000 for you primary battle rifle should be a good goal. And don't forget at least 10 magazines for each rifle.
Any secondary weapons don't need all that much. Maybe 250-500?
A shotgun have have a really good mix of buck, shot, and slugs, but perhaps not a huge volume. Again, 250-500? If you love trap, skeet, etc., perhaps you want more for those sports above the numbers I listed.
Good luck funding the purchases and finding the ammo...
