thread is too far developed for me to multiquote a bazillion people. especially with many things still developing, there's only so much speculation i care to partake in. that being said
1) i won't be surprised if bump stocks get regulated/banned. yes they "technically" keep a semi-auto firearm semi-auto, but the intent is to make them more like an automatic without adding a sear (which would make them full auto and subject to regulation). honestly i don't see regulation and/or ban being unreasonable (of course it wouldn't stop the truly motivated, the same way with sears).
2) there is no such thing as a gun show loophole. there is regulation (or lack thereof) of private party sales. i have no problem with universal background checks, but in return NICS should be opened up to civilians, not just FFLs. it's the netflix/itunes issue - make something so ridiculously simple that people would be stupid not to use it. make NICS readily accessible, cheap, and user friendly, and most people will be happy to use it. going through dealers is a PITA.
don't punish law-abiding gun owners (which is most of them) and make being a criminal preferable (see
https://www.washingtonpost.com/news...-gun-registration-law-ruled-unconstitutional/)
3) i get the point behind waiting periods. i think they're a little silly, but a few days isn't totally unreasonable.
4) "large" is a subjective term. standard capacity for many rifles is 30. for pistols, might be 10-15 depending on the caliber. so what is "large", and is it universally applicable to pistols and rifles? and let's just say we nationally took the CA approach (10) or god help us NY (7...which no one makes a 7rd mag), why chance turning so many law abiding citizens into criminals? that's literally what this kind of law does. it offers little social benefit and punishes people who, up until that magical point, were perfectly law abiding citizens before.
5) most gun deaths in america come from suicides (roughly 2/3). as much as this is a gun problem, it also speaks to the poor state of mental healthcare in the US, both from an access and cultural standpoint (no one wants to admit they are dealing with mental health issues and appear as "crazy").
6) of the majority of gun homicides, most are committed with pistols. so trying to ban all or certain rifles isn't going to affect the majority of homicides. in other words, it would largely be a feel good measure and a waste of a large amount of time.
7) what makes a hunting rifle a hunting rifle? is a mini14 with a wood stock a hunting rifle, while a mini 14 in all black an "assault weapon"? as an example -

i can most certainly hunt with my bolt-action 308, while many people use something like an AR15 in 223/556 for smaller game or, if you're in a rural place, hunting coyotes on farms and such. As best I can tell in quickly reading CA and TX hunting law, all centerfire cartridges are legal as long as they are not soft-nose/frangible/hollow point - this includes both 223 and 308.
Which one is considered the more dangerous firearm? like my AR15, my 308 has a detachable magazine but is bolt-action vs semi-auto. Does that make a difference? (in CA it does). The 308 round is significantly larger than a 223. Does that make a difference? The 308 round has a lower muzzle velocity (but maintains velocity better over long distances). Does that make a difference?
The point is, defining what is a "hunting rifle" and what is not is actually not straightforward at all, especially when there's arguably no reason why multiple types of rifles cannot be used to hunt different sizes/types of game.
-----------------------------
i won't say there is nothing we can do, but "prevent this from ever happening again" is not necessarily a health mentality either (example - mandating driver interlocks on all vehicles to discourage/prevent drunk driving accidents)
last but not least, i doubt any of the above will truly help heal the wounds of those who lost loved ones
