....magnetic after leaving the gun? You'd think there'd be some effect on it and the other bullets in the magazine.
Apparently not. After it leaves the muzzle it's SUPER magnetic, enough to instantly cause a 90 degree diversion to it's supersonic path, but is not even slightly influenced before.
Also bullets are made of lead, and lead is not magnetic.
shareThe father did say something about a steel core in the bullet. However, I think that was a future weapon so how would he have known that?
shareAlso bullets with steel core are the armour piecing rounds, why would they use it at all? The guy did not wear armour or bullet proof vest at all.
When the target not wearing bullet proof vest, armour piecing bullets are actually less lethal, because it increases the chances of shooting right through.
Maybe the weapon was just loaded with armor piercing rounds because the person who loaded it (I can't remember where she got the gun, maybe it was the henchman's?) wanted some options like shooting through vehicles or cover etc.
Anyway the point is about the selective magnetics, not about why the gun had that ammo in it.
True, the magnetic field so strong to turn the trajectory of bullets, then it would definitely have taken the gun out of her hands.
shareMost non-expanding bullet are made of bronze, steel and other materials that are harder than lead. Most 51 caliber bullets for the 50 BMG made for the military are steel core.
shareI didn't know that about .50 cal rounds, but yes it makes sense for them to be harder metal as they're made to disable vehicles and punch through cover etc.
shareGood catch. Pretty easy to explain away, tho. . .we don't really know how much the bullets weighed, or the gun, or how strong she was, or what future tech was involved in creating it, etc. . .
shareThat scene was rather sad as the magnetic field did not appear to affect the trajectory of the armor piercing bullet until it had traveled away from the muzzle, then it made a sharp turn towards the woman. Then instead of just poking a hole in her body, it appeared to have expended enough energy inside of her to throw her backwards.
shareI'm no expert at all about such things, but that magnetic field actually grabbed a high-velocity bullet like it was nothing. That much power should've just yanked the gun before she ever shot it.
shareIt could be argued that the future gun is ceramic or carbon fiber or something else non-magnetic
shareWhat would be the point of arguing that? We already know the gun is loaded with ammunition containing steel-core bullets, which means, "That much power should've just yanked the gun before she ever shot it," just as the guy you replied to said, even if it were a highly implausible hypothetical gun which has no steel parts (in this context the bullets are effectively steel parts once they are loaded into the gun, obviously).
Yep, when I answered there I made the assumption Tyler was talking about the gun itself being magnetic and being yanked because of that. Probably the wrong assumption on my part.
"even if it were a highly implausible hypothetical gun which has no steel parts "
I don't think a small arm in the future having no magnetic/steel parts is implausible. But yes, add magnetic bullets into the mix and it's a moot point for this scenario.
"I don't think a small arm in the future having no magnetic/steel parts is implausible."
You could make one right now if you don't mind it not lasting very long, for example, out of titanium. Titanium chamber throats and barrel throats suffer from rapid erosion compared to steel. For example, this is a titanium revolver cylinder after firing only 34 rounds of .357 Magnum ammunition:

Ceramics and carbon fiber / resin composites are terrible materials to use for chambers and barrels.
300-series stainless steel is more or less non-magnetic, but it's a poor material for barrels and chambers because it can't be hardened by heat-treating. Certain flavors of 400-series stainless steel make great barrels and chambers; it's been used to make lots of them for decades, but it's as magnetic as plain steel.
By the way, if the magnetic field is strong enough, it doesn't matter what it's made of, because everything is technically magnetic to one degree or another. It wouldn't be just the gun drawn to it; people and everything else would be drawn to it too:
