Hot loading refers to loading a round so that it generates faster velocities and pressure loads faster than the usual factory specifications IIRC.

Slicing the pie or pieing a corner is the term for rapidly side-stepping around a corner with the muzzle as the pivot point. It's used for moving quickly around a corner without exposing yourself too much AFAIK.

hollywood BS again?
Well it does obviously depend on the energy of the round. But, even the rounds a vest is designed to stop will depress the vest (and flesh underneath) a large amount when stopping a bullet. Most police vests are required to meet a certain spec regarding how far the stopped bullet depresses the vest. They test the vests using mannequins with soft clay on them under the tested vest. IIRC the standard maximum is 44mm of depression into the clay.

If you think about how far 44mm is into your chest, it is kinda scary and you can see where the bruises, bleeding, and broken bones come from. In the early days of vests in the police force, it could take some time before the doctor would figure out that there was no actual penetration by the bullet due to the injures received regardless.

Edit: thx jaunty, lol

Are you sure it's not 44mm? On a person who's of a normal weight and of average dimensions, 44cm wouldn't just go into him, that'd go THROUGH him.

Hey! I go around corners like that at school all the time. I usually get a good march going through the hallways, and if I don't sidestep I could easily slam into somebody coming the other way...

[edit] ...and to stay on topic, I heard today that some experimentation was done trying to make a pistol in .30 carbine back in the day, to keep fewer different cartridges around. Anyone have more info?

BAD TAQUE'S ROBAR..BAD ROBAR!
There have been a few firearms manufacturers that have made pistols chambered for the 'ol .30cal carbine round. Ruger's Blackhawk SA and the Automag III are a couple. I couldn't find more info on it, but I recall seeing an old Sears Roebuck catalog that my grandmother had that showed a Browning semi-auto chambered for .30 carbine also. Anyway, the pistol/rifle-same-ammo-combo thing has been around for some time. AND, like almost every new innovation that was developed for military use, when the war was over, they had to find a way to break into the civilian market. As the M1 carbine had become familiar to most of the population due to it's use in two wars, and it's small size made it more easily useable by women and teens, AND we were heading into the time of the cold war and the Red Scare (when the WHOLE American population was arming up for the inevitable communist invasion), it was a shoe-in for marketability. So a gamble was taken that handguns chambered for the same popular .30 carbine cartridge would sell like hotcakes. Bet somebody lost their job over that one :p

I have a question regarding the FN Five-seveN. I was checking out some pictures of the gun, and I noticed that there was no "button" for the slide release. How come? Does that mean that you have to do the cocking motion to release the slide when in locked position?

I dont' think single/double action has anything to do with it in this case. This is simply the way the manufacturer designed the weapon. I know little to nothing about the FiveseveN, however, so I can say no more.

perrin98: you're right, SA/DA doesn't affect the movement of the slide of a pistol, only the hammer and the trigger pressure, but for some strange reason, AFAIK, the double action version of the FiveSeven has a slide release, whilst the single action doesn't.

Two models

The Five-seveN® is a double action only pistol.
No decocking lever. No hammer to cock.
Safe to carry with a round in the chamber, ready to fire.

The Five-seveN® Tactical is a single action pistol characterized by a short, light trigger pull for fast accurate shooting.

Now that was hard to find :rolleyes:

OKies, whats the difference between an AK-47 and an AK-74.

Apart from the fact that 74 uses 5.56mm.

Also, are some weapons "military grade" what does that mean??
 

OICW

Reason & Logic > Religion
The AK74 fires 5.45X39 rounds, although you can get them chambered in 5.56X45mm. I know this is the case in the US in states where they aren't gun grabbers and some people want 5.56mm in an AK.

Apart from that, and a dual ported muzzle break (I'm talking about the original AK74 to keep things less confusing, not the improved variants like the AK74M), there isn't really that much difference. Oh, the AK74 has a stamped reciever like the AKM as well.

By military grade I assume you mean military spec: that is, weapons which are actively used by at least one military (the military either has to be of a reasonable size or has other militaries use the same weapon(s) it does). This basically means that since Inf is aiming for a military simulator, only mil-spec weapon suggestions would be accepted.

Okay, what about the XM177 and the M4.

And also, what about the M16 - everyone I know says it sucks. Just cos they are scared to single shot. But does it really? It was used for a long time by the US Army.

Finally, SA-80s - Maybe a british weapon in the game? What are the main advantages of this over other modern ARs, like the G36 and the AK47/74 ?

P.S. OICW - F0rking cool sig :D

Thanks, I think it sucks because of the size limit (I could change it, but I'm crap at photo editing, so it would look stretched and silly). It looked much better at 500X250 or whatever it is before.

The M16 is a nice assault rifle (this is only my opinion ;) ). The only main problem is that it uses a direct gas system: all the gases from the bullet blow directly on the working parts to cycle the action. The AK and G36 for example have a piston which is moved by the gas, so that the working parts don't get as dirty. It could be a bit stronger, but it's alright as long as you look after it well: same with all rifles, even the lovely AK ;)

The M4A1 carbine has been adopted instead due to the increasing urban environments where fighting is most likely to take place. Apparently the gas buffer is put under more pressure than the M16, so the reliability is a bit less. The biggest issue is with the shorter barrel though, with less effective range and
accuracy, but the newer 77 grain rounds being adopted solve that.

XM177 and M4: answered here:

http://forums.beyondunreal.com/showthread.php?t=118589

The L85A2, better known outside the British Army as the SA80 is a pretty good assault rifle. Tiffy knows more about it than I, but apart from a few teething problems, just like all new assault rifles have in the older models, it's pretty reliable. The pres has been in a frenzy over it, but it is accurate, if a bit rear-wards heavy from what I've read.

The G36 IMO is alright, except it's not as strong as the G3 due to the plastics, and the red dot sight has a tendecy to get fogged easily, and isn't too rugged.

The only difference ingame in Inf really would be the 4X SUSAT (Sight Unit, Small Arms, Trilux) scope: instead of a circular or triangular reticule like the newer ACOG scope models, it has a tritium "pointer" that extends from the bottom of the scope field of view. It can fire rifle grenades, but I don't know whether the Brits still use them or not in active service.

So do you think I should suggest the SA80 as a new weapon?

I like the SUSAT - Looked down one...Just think it would be nice to have something British for a change :D

They are nice to hold and feel good to fire. The game doesn't include jamming so thats not a problem (the A2 would probably be used anyways).

Oh, my first question wasn't finished, what I meant was: What is the DIFFERENCE between an M4 and an XM177.

well about the XM177 and the M4A1 look in your other thread. if you cant be bothered then here:

http://world.guns.ru/assault/as50-e.htm - XM177
http://world.guns.ru/assault/as17-e.htm - M4A1

at the most basic level, the CAR15, XM117 and more recently M733 are basically really short commando weapons while the M4A1 is a carbine weapon, which is a little longer. the commando weapons cannot be fitted with most of the M16/M4 attatchments because theyre too small - M203, etc.

and ive got a question too:
- are there actually any magazine poucher/dispenser things that allow you to reload with one hand (like in tomb raider (horrible movie :mad: ) and MGS3) ?

- and oh yeah how do scopes on firearms work? they look like they point parallel to the barrel and if this is so then surely placing your crosshaire over the target (eg putting the cross between someones eyes like in movies) wouldnt result in the bullet landing exactly where the cross is.... id be really interested to know what is really happening with such aiming systems....

Dr J- do you mean a pistol or rifle?

A pistol can be reloaded one-handed with relatively little difficulty for most pistols, it depends on where their slide release and magazine release buttons are located and how easily they are applied with one hand.

You eject the magazine (assuming the pistol is empty, if it's not, apply the safety), put the pistol backwards in the holster, or if that's not possible, hold it between your calf and thigh with your legs, take another magazine out, put it in and pull the pistol out and thumb the slide release (or take the safety off) and voila ;)

Btw, the US Army teaches that in case you have an arm injury.

For a rifle it'd be more tricker, depending on the design (the hardest part would be shooting it one handed), but I would imagine it'd be largely similiar to how you reload a pistol one-handed, except for the holster part :)

hey thanks OICW :) yeah i meant pistols. in tomb raider and it also looks like it in mgs3 - they just swipe the gun across their thigh holster and then its gets reloaded.. was wondering what was happening there... and oh so thats why pistol holsters have the grip sticking out ;)
