If you talk to hunters, they'll give you a long list of annoying laws.
California requires a background check to buy ammunition and prohibits state residents from importing ammunition. If you are a non-resident, you can bring ammunition in, but you cannot give it to anyone else and you cannot buy ammunition in California. This is such a common problem that many hunting organizations have guides explaining the issue.[1] When I lived in California, I was unable to buy ammunition despite legally buying several firearms. Around 1 in 6 legal gun owners in California are incorrectly denied when purchasing ammunition.
California (along with several other states) bans civilian ownership of silencers. Hunters need to be able to hear when searching for game, and they rarely have time to don hearing protection before taking a shot. So the net effect of this restriction is to give hunters hearing damage and create more noise pollution. It's also a problem for anyone in rural areas who wants to dispatch pests, as gunshots annoy neighbors and can even result in the police being called.
California requires that long guns be unloaded when transported, but the definition of "unloaded" states that ammunition be stored separately. If ammunition is readily available near the firearm, California counts that as loaded, and you are committing a crime. If you have a cartridge holder on your rifle's stock, it must be empty when transporting the firearm.
California requires that hunters use lead-free ammunition. Lead-free ammo is more expensive and less available than typical lead ammunition, especially if you're not hunting with a common caliber. This means that hunters have less practice with the ammo they're hunting with, and many hunters zero their rifle using leaded practice ammo. This makes hunters more likely to miss an animal's vitals, prolonging its suffering. Lead-free shot makes sense, but considering how few rifle rounds are expended while hunting, and how it's legal to use leaded ammo for target shooting in the wilderness, the lead restriction on hunting ammo serves no useful purpose.
It's been years since I lived in California, so I'm probably forgetting some other laws that annoy hunters. But believe me: hunters are not happy with the current laws.

If I own many firearms already, what exactly does a waiting period do besides infringe upon my rights?
But yeah, the benefit does mostly arise for first time gun buyers. But that would require a master list of all gun owners. I'd prefer the wait per gun.
I'm talking about saving people's lives here.
As far as the waiting period, there's a perfectly valid reason against that as well... if you are under eminent threat of violence from someone and want to be able to defend yourself/family/home today... it stops you from being able to do so.
I am okay with the (relatively quick) background check... when I bought my first guns a few years ago, I had to wait about an hour in the store for the results to come back (Phoenix). Even then, I'm not okay with secondary offense restrictions (weed, etc) as a restriction.
