Just saw the movie "Shooter"

opening sequence when he shot down the chopper
if you recall he used a barret m-82 which is a semi-auto 50 cal so why did he have to cock it after each shot? because he was shooting blanks which do not generate enough pressure to cycle the action. so tell your friends marky mark shoots blanks!!
 
Book was a great read.... but as a whole, I was pleasantly surprised by the movie. Certainly worth watching.
 
Nope, they clearly show the action and it's an M82. He doesn't even reach up to recock it on each shot, they just dub a cocking noise over the action.
 
I haven't seen the movie. In the book he takes out the firing pin, cuts in in two to shorten in, and welds it back together so it will look right but won't fire.
 
cheytac's calculator that they give you with the cheytac intervention calculates for spin of the earth, although the actual error in shot is probably negligible.

i really wanted to call the bs standing up on a moving boat head shot from like 100 yards.

I still have a hard time understanding how the rotation of the earth could affect my toilet. I understand something big like a hurricane, but a toilet????

it does not affect your toilet, that's a simpsons myth.
 
I don't think the M82 has one, but if a semi-auto rifle had a gas shutoff, would it not A) make the harmonics more amenable to long-range accuracy, and B) prevent giant shiny cases from flying 10 feet?

i just did a calculation based off

http://atm.ucdavis.edu/mmg/atm60_2005/note/coriolis.pdf

for a 2300 meter shot (the distance limit of cheytac 408's supersonic capacity).

distance =

2300 meters

we need the muzzle velocity =

305 grain (19.76 g) Copper Nickel Solid: 3258 ft/s (993 m/s)
419 grain (26.95 g) Copper Nickel Solid: 2900 ft/s (884 m/s)
419 grain (26.95 g) Copper Nickel Solid: 2750 ft/s (838 m/s)


terminal velocity will be speed of sound (roughly) =

340 meters per second

mean flight velocity (this is a conservative estimate of how fast the bullet is traveling, with this estimate the friction with air is overestimated) =

305 grain (19.76 g) Copper Nickel Solid: (666 m/s)
419 grain (26.95 g) Copper Nickel Solid: (612 m/s)
419 grain (26.95 g) Copper Nickel Solid: (589 m/s)

rough flight time based on mean flight velocity (this is very inaccurate as the faster traveling bullet in the beginning covers much more ground and flight time should be significantly less, but this is conservative in the sense of maximizing coriolis effect) =

305 grain (19.76 g) Copper Nickel Solid: 3.45 seconds
419 grain (26.95 g) Copper Nickel Solid: 3.76 seconds
419 grain (26.95 g) Copper Nickel Solid: 3.9 seconds

angular velocity =

7.292 10^-5 rad/s

latitude of america = 40*

i got a .43 meter error if not accounting for coriolis force using the 666m/s mean velocity (best case sceario, fastest round), so it is significant.
 
I enjoyed the movie, especially when that anti-gun POS Danny Glover getting it in the end..:evil:

Gun are OK with these Hollyweird types to make their Millions with, but after that thay want to disarm the rest of us pee-ons... of course they have armed body guards..
 
Just saw it last night. Very interesting, with good detailing.

FWIW, I've taken Storm Mountain's Long Range Rifle course (unknown distances approaching 1000 yards).

I'd say about 3/4ths of the technical content was accurate and interesting, leaving a quarter which was bunk. The latter was eeither excessively overstated or just plain wrong, either to be impressive or to not become a training manual.

Remember:
- it IS a movie
- it must be accessible by a general audience
- technical accuracy must ultimately give way to a good story

In no particular order...

CAUTION! SPOILERS!

"Fire when ready" was frequently used, instead of "send" (term taught at Storm Mountain). Probably made more sense to most viewers.

The opening scene showed the importance of never firing more than twice from one location. Once your opponents figure out your general location, they'll throw an awful lot of firepower your way. Sometimes "spray and pray" is the only option ... and sometimes it works.

The big deal about the Barrett 82 is that it is semi-automatic: an operator should know that you don't have to work the bolt for each shot ... or something is wrong with the thing if you do have to.

There were a few scope-view shots that plainly showed the target much bigger, clearer, and steadier than is realistic. Even thru a great scope, you won't see a mile-away Spam can fill your reticle that much. Let's chalk those "mistakes" up to catering to the audience, who needs to perceive the visual quickly without lots of background (that shimmering bouncing red/blue dot is, in fact, a Spam can).

The most impressive to me was the very brief throwaway scene where, while scoping out one city, our hero tosses something in a trash can and gets in a cab. Few would notice the scene, much less that what he put in the can - and was sticking out flapping in the breeze - was actually a makeshift wind gauge for long-distance observation. This is vaguely referenced later when such analysis of suspect situations is described.

Most - but not all - of in-scope views included mil-dot reticles (or slightly stylized versions thereof). Some were plain reticles. None, to the director's credit, were weird busy reticles including exotic dynamic computations & displays.

I'm not sure what to say about a reference to custom hand-turned solid copper (?) bullets. Maybe someone else can weigh in on this, esp. for the .408.

Someone would have to go thru a LOT of work to arrange a conspiracy requiring recovery of a single bullet from such a remote backstop.

Some day I'll have to sit down and compute the relevance of the Coriolis effect. At Storm Mountain we were emphatically instructed that it is irrelevant. Sounds impressive, though.

The target showing the ~1" grouping at 1000 yards is, under unlikely confluence of all statistical variations, possible. Some very talented people have managed to do it, more than once.

I have my doubts about the remote-control platform. It may or may not be precise enough, and much of "sniping" is that innate feel that goes beyond straight mechanical precision.

A number of times, the story relied on unfair surprise elements - as in we as viewers were given absolutely no indication something critical to the plot had been done at a time we could/should have known, nor could we have reasonably expected it to happen. This, in storytelling, is cheating. A good thriller may make such critical subtleties subtle indeed, and identifiable on second (or even third) viewing, but "deus ex machina" solutions are a sign the author wrote himself into a corner he couldn't get out of without making stuff up. The firing pins, audio recorder, and a few other little things crucial to our hero's survival just kinda magically appeared after the fact as if we all should have known/expected, but we (a reasonable audience) didn't.

The "thru the scope" snap shot is simply a staple of "sniper" movies. Like it or not, feasible or not, you're going to see it.

Driving backwards into the bay was smart. Being braced by the full seat, instead of just the narrow seat belt (or nothing at all) is right.

Some day I want to drive a car thru a chained chain-link gate. So many movies (not all!) show it so easy that I want to see how likely it is.

The AG's final quote was great.

Good movie. I want to watch it again, slowly, taking notes & asking questions.
 
I watched the movie first then read the book. I liked both, yeah there are the silly hollyweird goofs, but whatever, no big deal.
 
I fell in love with Stephen Hunter after reading Point of Impact because of "Shooter."

The first two Bob Lee Swagger books, Point of Impact and Black Light, are absolutely great. The third, Time to Hunt isn't bad.

Of course Bob Lee Swagger is based loosely on Carlos Hathcock. Which is why he's a "Gunny."
 
I just saw it on blue ray, where I was able to pause, rewind, review, and explain details to my wife, much to her consternation. All in all, I thought they did a very good job. They even presented the laed necessary to make one of the shots in the early Africa part. Agreed, many of the magnifications were too close up. The EDM rifle in the movie did sport a Nightforce scope. Nightforce make a 12-42x56mm scope that will bring things pretty close. I can read the fine print on my targets at 100+yds, but no way I can read the Dinty Moore can at a mile!
 
yup... i watched the movie to check on that... he said"

5 shots group at 1000 yards 1.5'' spread... lol

Keep in mind, Swagger is ex-military, which explains away why only he can get mind-boggling impossible groups that us mere civilians shouldn't even dream of obtaining :neener:
