All I can say for sure, is I have about as many guns as I'll ever want - way more than I could ever need - plus around 10k rounds of factory center fire ammo and another 50k worth of reloading components.
So the left can kiss my backside. Unless and until they are ready to start forceful confiscation, there ain't SQUAT that they can do to affect my supply.
Never underestimate the lengths to which some folks will go. A few possibilities come to mind:
1. Licensing of reloaders as ammunition manufacturers.
2. Taxes on every round produced, perhaps more taxes on every component.
3. Changes in state and local codes restricting the quantities of ammunition, primers, powders, etc, may lawfully be kept in a residential dwelling or building (saw this in the Denver metro area a couple of years ago, 1000 rounds max per building, and that included a building with dozens of apartments all subject to the aggregate limit for the building).
4. State insurance commissions (appointed officials) changing requirements for insurance policies sold within the state to specifically limit or prohibit any insurance coverage for damages or injuries resulting from ammunition storage, components, reloading, etc.
5. Prohibitions on possession or use of lead bullets or shot.
6. Changes in laws dealing with child endangerment to prohibit possession of ammunition, components, or reloading equipment/supplies in any household with children present (or perhaps within 1000 feet of any child's residence, or any school, or any day care facility, etc).
7. Changes in business or zoning laws to prohibit sale or delivery of reloading components, supplies, or equipment (or just onerous and expensive licensing and compliance requirements).
Then there is still the United Nations Treaty on Small Arms floating around, which the US might conceivably ratify at some future time. That treaty contains strict licensing provisions and other restrictions for anyone who manufactures or reloads ammunition (not to mention firearms of any type in private hands), which might be found palatable by those who wish to limit your supply or access.
It can be amusing when a news source reports a story of someone found in possession of "an arsenal" or "thousands of rounds of ammunition". Probably not so amusing when the photos or videos show your house. You and I might think a few thousand rounds is just a reasonable supply for our range trips or recreational shooting, but that is probably not how we will be portrayed to the general public. We might expect to get a call from State Farm telling us our homeowners policy has been cancelled shortly after those reports are published.
As I recall, the Second Amendment uses the word "arms" with absolutely no mention of ammunition or the means for producing ammunition. I don't want to be the test case in court!
No, I will never underestimate the opposition.
