4th grade math is enough to figure out the difference in drop.I am very concerned about the technicalities.
We will need new scopes and bullet drop charts.
People need to get on this ASAP.
Well, some people might need a new scope who have the ACOG. It has hatch marks for differences in range and bullet drop.4th grade math is enough to figure out the difference in drop.
Why would you need a new scope?
I dont have an ACOG. Is the scope calibrated for the specific barrel length, gun and bullet weight from a specific manufacturer?Well, some people might need a new scope who have the ACOG. It has hatch marks for differences in range and bullet drop.
I can probably get by with my Aimpoint Pro, or T2, but as of now they are not Lunar Certified.
I pay extra for "mil spec", "NV / IR Capable", "Tactical", and "Lunar Certified".
Even if I'm not going to the moon, I want what THEY have.
Recoilless bb pistol is the way. Even on the moon, unless you have a rock behind you, ya gonna move a bit.NASA did a study on such things back in the day. Without looking it up, I seem to remember the gun 'should' fire.
I'd assume then that they'd be relatively effective since all you need to do is puncture the suit and get behind cover and let physics kill the other person.
again, easier than I thought it would be, Cornell article on the subject:

I would like to hear from an ACOG owner, because not every ammo is the same. So I find it hard to believe that sight will be spot on with all the rounds from different manufacturers.
I've seen AR trigger guards that 'bow out' and give more room near the trigger.You guys are all thinking about gravity, oxygen and atmospheric pressure.
My first thought is, "how am I going to get my fat space suit finger in the trigger guard?
Yes, a common misconception is that guns wouldn’t function underwater. While drag forces would greatly affect range, some guns most certainly would be able to function with greatly reduced muzzle energy. But with increasing depths and increased pressure I am sure the gas systems of most firearms would be disrupted sufficiently to render operation impossible.
Shooting under water has the same questions to answer but under greater pressure...

It will be fine for a few minutes until your finger freezes.I've seen AR trigger guards that 'bow out' and give more room near the trigger.
Or, just cut the tip off your glove like here on earth. I'm sure it would work fine.
So with a space suit and all, if I could pick up a hundred pounds over my head, would I easily be able to pick up 600 pounds over my head on the moon, regardless of shape of object?Any weight a person has on earth can be calculated with the formula Weight = mass * value of gravity. Well your mass will stay the same on these different planets but the value of gravity will change which implies your weight will change on said planet. So calculations to bullet drop will be changed since the weight has also changed in the necessary formulas.

It still has mass though.....MxA=F.So with a space suit and all, if I could pick up a hundred pounds over my head, would I easily be able to pick up 600 pounds over my head on the moon, regardless of shape of object?
You would be able to carry the object since that G is proportionally inverse to the mass increase. So all things are equal through system changes and you would be able to lift the object.So with a space suit and all, if I could pick up a hundred pounds over my head, would I easily be able to pick up 600 pounds over my head on the moon, regardless of shape of object?
Brass rats don't approve.DI is still scavenging gas from the firing cycle so it should be fine. That said, yes a bolt should be more reliable.
If it's and AR you simply open the trigger guard. I think most people are unaware the AR is specifically designed to open the guard to fire with heavy gloves on. That's why the trigger guard has a spring retainer on one side that can be pressed in with a bullet tip.You guys are all thinking about gravity, oxygen and atmospheric pressure.

M.O.M...Minute of Moon!Range would increase, presumably. The Moon only has 1/6 the gravity of the earth, so for any given range at which you could expect gravity to contribute to bullet drop here on earth, just multiply by six to get the moon distance.
Of course, everyone knows an AK would be a better choice as a space weapon (and everywhere else). I don't have the knowledge to tell you what reduced gravity and/or lack of oxygen would do to the gases in a direct-impingement system, but I'd imagine a piston would be more reliable. A bolt-action is probably even better.
I own one and while it’s close you have to re-zero changing ammo just like any other scopeI would like to hear from an ACOG owner, because not every ammo is the same. So I find it hard to believe that sight will be spot on with all the rounds from different manufacturers.
Anyway, the moon will be won over with AK47, just like pretty much every war. So Iron sights all the way.
Six Minutes of Angle?M.O.M...Minute of Moon!
Wouldn't an ak be worse due to the looser tolerances.Range would increase, presumably. The Moon only has 1/6 the gravity of the earth, so for any given range at which you could expect gravity to contribute to bullet drop here on earth, just multiply by six to get the moon distance.

Right. BDCs are ammo and barrel length specific. For example, the Vortex BDC is for (IIRC) M855 in a 16" barrel.I own one and while it’s close you have to re-zero changing ammo just like any other scope
All firearms function by sealing the barrel.Wouldn't an ak be worse due to the looser tolerances.
I thought the reason an AR would fire would be because the casing sealed the chamber and propelled the round.
But seriously what the hell do I know I'm just an IT who got less than 3 hours of sleep and spent all day chasing a 9 month old around.
Far more than that, as the arc of the bullet would be a smooth parabola as there would be no aerodynamic drag.Range would increase, presumably. The Moon only has 1/6 the gravity of the earth, so for any given range at which you could expect gravity to contribute to bullet drop here on earth, just multiply by six to get the moon distance.
The producers actually apologized for that afterwards, saying they should have researched itOne thing that always makes me laugh is the scene in Firefly where Jane puts one of his rifles into a spacesuit when he needs to shoot it outside the ship.
YesI expect that the distance traveled would exceed the proportional difference due to differing gravites as there would be zero wind resistance and no drag.
It would be effectively the same.What about recoil?
