Why are these are biggest bullet for handheld weapons? It should be easy to make a bigger bullet, you just need a bigger gun!
"Why are these are biggest bullet for handheld weapons? "Recoil?
some guns direct the recoil downward so the recoil connot be felt if you want a higher caliber handgun even though i would call it a hand cannon it would have to be no smaller than a military issue 50 caliber sniper rifle unles you want a gun with twice the recoil of a desert eagle handgun
The problem with high calibre bullets is aerodynamic - it will lose a lot more energy to drag, and so have a shorter range and less precision, than a bullet of similar mass but smaller calibre.
Certainly, but usually higher calibers bullets have greater mass too, with a similar shape; considering for simplicity a bullet of cylindrical shape; if the caliber double, the cylinder diametre and its lenght become 2 times as before, so the bullet's mass becomes 8 times as much. This means, with the same bullet's speed, an 8-fold momentum, but only a little more of 4-fold air friction (bullet's section is 4-fold) and so a greater range and higher precision, actually.All this, I repeat, with similar bullet shapes and speeds and of course using a similar gun; you can't do this kind of comparison between, e.g., a 5.56 mm M 16 and a 12.7 mm XVIII century gun.
Yes, but to maintain the same speed, you need 8 times the charge, and thus manage the commensurate increases in stresses on the gun barrel and other mechanisms.
For a given limit to the stresses a gun can take, an 8 fold increase in mass would need substantial reduction in velocity (but a reduced velocity will still require a slower burning charge).
Nonetheless, if you do want an increase in mass, it is just as easy to design a longer bullet as a thicker one (especially if you are using expanding bullets, but it may be a more complex issue if you are shooting at a hardened target that you want to penetrate without expanding on first contact).
