Not sure a .22LR will do a lot of damage at 300 yards. However, I wouldn’t stand 300 yards away and let you shoot at me so I could prove my opinion.
There is no reason one person needs that many guns. But the Constitution doesn’t say a reason is needed but fighting off a tyrannical government that’s trying to take away the people’s guns is a very good reason.
That's a very slippery slope. You must never surrender to the mindset that some other person is better qualified to decide what you need and may possess. If you purchase a desired item with the fruits of your own labor and do no harm to others, there is no moral reason to surrender the ability to choose for yourself.
There are a multitude of reasons to have many types of guns. A .22LR is fine for a rabbit, but totally inadequate for an elephant or bison. A 460 Weatherby is fine for an elephant, but would spatter a rabbit. You choose the right tool for the task. Usually just one from a potentially large collection suitable for various purposes. A double barrel 16 gauge shotgun is just right for dove. A skeet shooter wants a 12 gauge semi-auto to engage two clay birds from the high and low house. Shooting steel silhouettes is done with long barrel pistol or revolver. A concealed carry pistol or revolver needs to be small. If you do all of those things, you might well have a large collection. Each suited to its purpose. The rest securely locked up away from children and thieves.
People collect things. Dolls, coins, shoes, sex toys, lunch boxes...
Quality firearms are generally a good investment, especially if in mint condition.
I know folks with hundreds of guns and I will bet my last Nicole that they will never commit a gun crime.
There is more to this story.
"Because I want them" is sufficient reason. You probably have no idea how many guns your fellow FReepers have.
