Geez. Lots of misinformation here.

Use Caliber particular blanks and spray WD40 down the front barrel ( extremly short spray) wear gloves and eye protection have buddy standing next to you with fire extinguisher
Um, no.

All fire blanks, blowback operated dont need a BFA....use blanks with plastic bullets that burn up in the air almost instantly
Um, no.

In some movies there is a special BFA that can be 'hidden' in the barrel of the gun, only visible when looking straight down it. These are different to the normal HUGE BFAs that go over the flashhider when blanks are used for military training. I realized this while watching 'Clear and Present Danger' when the soldiers are in the jungle and one points his rifle more or less right at the camera and the BFA is visible inside.
Correct. Most movie guns are plugged this way.

Guns that actually do fire blanks have to have the barrel plugged unless they're manually operated firearms. A blowback automatic weapon will not cycle if there is no inertia from moving a bullet since it is that which provides the force necessary to blow back the bolt (remember Newton's 3rd Law?). A gas operated firearm needs a barrel plug in front of the gas tap to create enough back pressure to cycle the bolt. Revolvers, bolt actions, pump actions, and lever actions don't need barrel plugs to function with blanks.

A blank load is a standard brass cartridge case sans bullet, typically rose crimped to resemble the bullet it would normally be loaded with so that it will feed properly in a magazine. This sometimes necessitates using brass other than the chambered caliber so the neck of the casing can be crimped into a bullet shape. Provided the head is the same diameter and thickness you can trim the length as needed and fire form the shoulder as required.

The powder used is a special blend formulated especially for firing blanks and is extremely quick burning. Using it to reload any commercial cartridge with a bullet would be disasterous. This, coupled with the specialty of manufacturing blanks in some esoteric calibers for oddball guns you might find in a war movie for instance, results in them costing a good $1.00 to $3.00 a piece. In Saving Private Ryan the beach sequence apparently used something like $100,000 worth of blank cartridges.


Very, very few recent movies use actual live (or converted) FA firearms... Just too much liability...
Also correct. Anyone find it interesting how Stargate SG1 always gets the latest and greatest firearms that just so happen to coincide with Tokyo Marui's release dates? Their current weapon of choice I'm told is the MP7. You can bet they're not using real ones.
