Don't you actually need a working chamber and barrel to use blanks ?
So make a caliber that's only used for prop guns and blanks.
The trick is getting the whole industry to standardize on it
This is pretty much 8mm, which is widely used in blank guns already.
Then you’d want it in every style of weapon, including historical
Well, yeah. probably most difficult in guns that were historically muzzle-loaded
You don't need a working chamber at all; with modern cgi you can make it indistinguishable from the real thing.
Well while that's a pretty great video, it's definitely not "indistinguishable".
I mean, you are correct that it can be made indistinguishable, but this youtube skit ain't that, although it's pretty fucking hilarious.
Clearly ″indistinguishable″ was meant here as a joke
You're very likely correct. I'm fron the 80's and while that might have been clear to you, it wasn't to me.
I apologise.
It's just very high quality compared to the jokey videos we were making at that age with camcorders and no pc's.
You have been forgiven. Here is a somewhat gun related sketch from WKUK that is even more HQ, but that is expected cause this was on TV, episode aired on 2008.
I miss the Whitest Kids You Know.
My favourite is still the PCP skit
Giggled like a motherfucker last week when my brother showed that to me.
It's a rough world in business, innit?
Gus has fuckin mastered the cigarette-hanging-out-of-your-mouth-while-you-talk thing
Yeah, blanks are for guns, a lot of gun fire is post processing anyway, so idk, I'd think the risk wasn't worth the end result.
They fix everything in post anyway; why do they have to fire blanks and not just cap gun caps?
If nothing else, recoil.
Blanks have less recoil than live rounds anyway, a large part of the recoil is due to the weight of the projectile.
Sure, but having something actually happen when the actor pulls the trigger gives them something to react to. These aren't impossible hurdles but shooting blanks is way easier.
There's also safe ways to do everything, like don't point it at someone, point slightly upstage so it appears you're pointing at them from the camera angle, for instance. Or not having live rounds on set.
Or, y'know, requiring the actors to become familiar with their real gun and double check safety before they use their real guns (a 15min lesson) because redundancy saves lives (the problem with that is actors pretend they're too stupid to learn 15min of safety procedures before doing dangerous things and they would prefer to do dangerous things without fully understanding them. I think that's a bad idea, personally. If I'm using a real chainsaw in a movie I'm gonna learn how to not chop off my own fucking leg as a part of learning my lines, because I like my legs. Same for if you pass me a blank firing gun, a real bullet in the mag turns that into a grenade in my hand, best fucking believe I'm checking, I like my hands!)
They're actors. Just pretend. 🤷🏻♂️
Yeah but you could use a different caliber that's nonstandard.
True. I guess they don't do it because they'd basically need 1 nonstandard "blank only" variant for each actual caliber, otherwise the bigger gas/blowback-operated guns might have some trouble cycling ?
Yeah in my mind it'd be a "blank-only" gun, a movie prop. Which is well within the budget for movies like this, I mean they have a dedicated armorer. Resizing a barrel isn't uncommon, based on Wikipedia searches, so while it might be a hassle, it could definitely be done within a reasonable timeframe and cost, and avoid any mechanical issues with the gun, but would be pretty high on the list of things a movie would cut corners on if it decided to.
Which is what I gather happened here, anyway, so maybe this IS standard practice.
Yes and no. There are both but real guns are typically used for hero shots because they have the right weight and make the right noises.
There's also blank firing adapters for some weapons which are fairly big and obvious but essentially split the round in two as it exits the barrel and mushes them up so they lose all their energy.
https://en.m.wikipedia.org/wiki/Blank-firing_adapter
That's not really what BFAs do, at least not the models I've used. You seem to imply that weapons with BFAs fitted are still firing real rounds, which are rendered safe by hitting the adapter. That's not true. They are firing blanks, which are cartridges with the bullet and some of the powder removed. Pull the trigger, you get a pop, a flash, and some smoke. Yay!
Pull the trigger again though, and you're very likely to have a misfire because the next round failed to feed from the magazine to the chamber. This is because most semi or fully automatic weapons use some of the energy of a fired round to cycle the action which expels the spent cartridge and feeds a fresh round into the firing chamber. When you fire a real bullet, it actually acts as something of a plug in the barrel for the very brief period of time it travels through it. This allows the pressure to overcome the resistance of the weapon's action, and thus operate.
When you fire a blank, there's no bullet. No bullet means no plug, which means that all of the gas from the explosion just rushes right out the end of the barrel and is not enough to cycle the gun. This, you have to manually run the action, turning your scary big black assault rifle into a quaint bolt action rifle.
So, how do you solve this problem? You make your own plug and stick it on the end of the barrel to redirect all of the energy through the weapon system rather than expelling it. That's a all a BFA is, a metal post matched to the diameter of the barrel that screws into place to plug it. This has the additional positive of preventing anything from exiting the barrel accidentally while firing blanks, which is useful in the training contexts that you often see these devices, because you're often "firing" on other people.
If you were to use a BFA in the manner you describe, i.e. with a real bullet, you're certainly going to damage the shit out of your weapon, and possibly wind up in the Emergency Room because you caught some metal splinters in the face when the end of your weapon exploded.
They aren't wrong though. There's different types of "blanks". There are blanks which are completely "blank", but there are also "blanks" which just have a regular shaped bullet, but a very light one, made out of balsa wood, and those do require a blank-firing adapter and while they wouldn't fly far from the barrel, you could hurt someone with one probably, but more importantly the blank-firing adapter also restricts the gases which are let out, thus increasing the (otherwise inadequate) pressure on the reload mechanism, so you don't have to manually reload. In fact, we here in Finland call it "sysäyksenvahvistin", and the direct translation wouldn't be "blank-firing adapter", but "increaser-of-pushback-pressure", more or less.
It's easier to make blanks like that than it is to make ones which don't expel anything and still manage to keep a semi- or fullauto reloading.
There's a mandated 50m safety distance for these, but I once got shot in the face from less than a metre a way while we were practicing urban warfare. I was spitting balsa wood for the rest of the day.
One dipshit ones had blanks in his mag, didn't have his safety on, didn't have his blank-firing adapter installed, and the gun was fucking loaded. Sure it probably wouldn't have killed anyone, but that shit was still dangerous.
Soooo yeah, it is exactly what certain types of blank-firing adapters do.
I'm a little confused by your response. Everything in my post was written from the perspective of firing the type of blank I described (no bullet, balsa wood or real) with the BFA attached. While I have had that type of blank cycle the weapon without a BFA attached, it's the exception to the rule.
Furthermore, would you clarify the use of these balsa wood bullets for me? Because, given my understanding of BFAs and what you described, I don't see how those two concepts would work together. As you said, the principle behind BFAs is plugging the barrel so more gas is directed to the action, rather than our of the system. If you had a BFA fitted to a weapon that was firing blanks which were tipped with wood or some other fake projectile, my assumption would be the debris would collect in the end of the barrel behind the BFA post. Hell, that's why we always hated training with blanks, it was always a nightmare to clean out the carbon buildup in the weapon after since none of it was expelled in the firing process like it would be in normal operation. Compacting a shit load of debris in the barrel of your weapon does not seem like it would be the intended outcome of a training event, but dumber shit has happened.
I am sure that there are blanks (especially in the context of a Hollywood armory) which are designed in such away to more closely resemble real ammunition, I've just never worked with something of that ilk, and it doesn't jive with my (limited) understanding of how firearms work.
Why do you assume how it works instead of just simply looking it up?
The blank firing adaptor isn't solid. There's an opening, but not a direct one. Thus the balsa wood bullet will be broken down into little pieces which will be ejected through the BFA, making room for the next bullet.
"If you had"
You don't have the balls to say "you're full of bullshit and don't know what you're talking about", but you're still trying to say that, when you could've just actually googled this.
"It doesn't jive with my ignorance", yeah, and that's probably what should propel you to seek more information on the matter instead of thinking your assumptions are correct, isn't it?
If the cops didn't bust me for weed and take take out all the other stuff I had while they were at it, I'd still have a few of those blanks to show you from my army days. It just really upsets me that you would rather assert that I'm in the wrong than be open to learning more. It's just... so American.
edit here's an image of the type of bullet I'm talking about, but this one is Swedish
OP described something which conflicted with my direct, personal experience with that thing. I offered up my perspective. You responded with your perspective, based on your own anecdotal evidence. Yes, I could have run off to Google to fact check you and learn of all of the types of BFA that are out there. I chose not to. Why? Because we're in the comment section of an article that has NOTHING to do with blank firing adapters. I assumed, and I guess you're just going to have to forgive me for not researching in advance enough to not make this assumption, that, in responding to my post, you might be interested in further expounding upon the statements you made and answering questions I had about how your devices worked since they were clearly of a different design than what I had experienced. On the topic of assumptions, I was very clear that I was making an assumption so as to make it painstakingly obvious that I wasn't trying to say you were WRONG ON THE INTERNET, but just that I wasn't clear on how the device you were describing could be functional, given my previously stated understanding. I even attempted to reinforce that I wasn't trying to invalidate your assertions by stating I was certain that wood tipped blanks were a real thing, I just had no personal experience with them.
So, I dunno what to tell you man. I tried really hard to be as non-confrontational as possible in my comments. I'm tempted to say that I clearly failed in my ambition there, but no, I don't think I will. You responded like a dick, and I think you ought to ask yourself what you're doing in a discussion forum if your first response to a comment asking for you to clarify some of your statements is "fuck you, Google it."
So yours is "direct personal experience" and mine is "anecdotal evidence"?
Just like I said in my first comment, while you might be unaware of all types of blanks, that doesn't mean they don't exist. So rather than ask or research, you implied or even downright refuted the existence of such ammunition.
Why?
You didn't ask "oh, how do those work vis-a-vis this thing", you said "oh those would clog up your barrel", because the BFA you used was different from the one we used.
Be open. Ask questions. Don't say "that would cause X". It sounds a bit like Flat Earthers who make weird claims about how far you're supposed to see into the horizon.
Yeah, I was too confrontational, I admit that, and I apologise. The lack of tone of voice on text based messaging can be a bitch, but honestly, I feel like you weren't being too open to types of weapon accessories that aren't common in your part of the globe. (See how I snuck "globe" in there to piss off any would be Flat Earthers reading this. Also, I've had about bottle of Bacardi.) Being neutral online can actually lead to people perceiving your comments as hostile. Fucking annoying, innit?
