Didn't make it yesterday, so went today.
Good movie, with a cool twist at the end.
Little curious about the "guns and springs being 30 years old" comments, geez how many old surplus guns (and ammo) are being shot everyday right now that a looooong past that age?
My comment so my explanation is this:
Surplus ammo and C&R pistols and rifles of any quality have been stored in cosmoline or under ideal temp and humidity conditions. That would not be the case for any firearms after a war "that tore a hole in the sky."
Most commercial primers are not sealed. Modern primers, containing no hazmat like the mercury in the old style mercury fulminate primers of old begin to chemically deteriorate at the 30-40 year span, rendering them inconsistent or inert.
On an autopistol, both magazine springs and recoil springs are critical to timing to prevent feed jams and extraction failures. It is commonly recommended that one replace a recoil spring at 5000 rounds or sooner and magazine springs as required.
Now transport all of these firearms not incinerated or damaged by the circumstances of war 30 years into a future that has no climate controlled warehouses, nice humidity controlled safes, working desiccants, new wire spring manufacture and wonder how many cannibalizations would have had to be done to keep many popular semiautomatic pistols up and running
in perfect working order with ammunition that works reliably. Then imagine the current condition that many if not all of the surviving firearms in a world where life was nasty brutish and short and ownership very fluid, after those guns would have been used hard and cleaned little, seen temp extremes of heat and cold, exposed to rain, and having their finishes worn off.
Not to mention where one is going to get any quality petroleum distillates for lube/ corrosion protection during the 30 years after refining stops.
Then calculate the odds on how many of these survivors would be semiautos, or RPG-7 grenades, all congregating in one place at one time for a big Hollywood shootout (haven't seen this film) and I'd think you'd find them to be fairly remote.
I would expect in such a world that long term surviving firearms would have a few common characteristics:
Commonality: There are millions of .38 Special revolvers running around out there from the turn of the 20th Century to today. There are tons of .30-30s out there too.
Lower volume of fire: A weapon with less of a post apocalyptic fire fight workload is likelier to survive with little or no maintenance over the span of thirty years than one which was coveted by every bad guy out there and many of which would be parted out for better working examples. Double action revolvers, low cap bolt rifles, double barreled shotguns, and other slowly reloading weapons would see less warhorsing into dysfunction.
Durables: Bolt rifles are a good candidate, as are single shot rifles, and anything else not terribly magazine or spring wear dependent for proper functioning.
Oddballs: The less desirable a piece is would oddly enough go longer towards ensuring it's long term survival, like a Glock using .45GAP. You just might not have anything to fire from it.
Easy runners: Flint lock muzzle loaders could keep going if folks figured out how to make good black powder. Hammer fired shotguns might be convertible to black powder. Of course black powder revolvers might come into vogue again, but the problem of making stable primers would rear its head again if caps were required.
. But as for reveiws on Rotten Tomatoes. They suck also. They gave District 9 90%+. IMO it should have reached such high praise. It was pretty much crap. I will take a decent action movie anytime.
