Recoil operated uses recoil from firing to cycle the action. Gas operated uses gas from firing to cycle the action.
Yes, but they will fire as a single shot. Unless the pistol is modified, it will not cycle when fired. These guns are recoil operated- and blanks do not produce significant recoil.
yes, paintball guns do have recoil, but no where near a real gun.
The quick answer is a .410 bore - but there are relatively low recoil 12 ga. guns as well. Browning made a "recoiless" trap gun which almost is recoiless. In general, a gas-operated semi-auto will have less recoil, and in some cases this can be combined with a recoil-absorbing stock.
Yes, smaller guns typically have more recoil compared to larger guns due to their lighter weight and shorter barrel length.
No, ALL small guns don't have recoil problems, but most do.
Not all guns have a recoil spring. In the case of guns like the 1911A1 .45 cal pistol, when the gun fires, the slide is driven back by recoil (kick). The recoil spring is compressed, stops the slide from moving back, and pushes the slide forward for the next shot. Is does not make the gun recoil less.
assuming that you talking about a .308 Winchester or the 7.62 NATO round recoil is factor of pure physics the lighter the weapon the greater the free recoil (kick).the heavier the bullet the greater the kick. the higher the velocity the more kick.there are many factors involved in calculating the recoil of any firearm.what does the gun weigh ?what is the barrel length? what is the bullet weight? is the gun a bolt action or auto-matic ? is it gas or recoil operated ? does it have a recoil reducer of some type? how effective is this recoil reducer? knowing the interior ballistics of a cartridge is only the beginning of calculating the recoil and barrel flip of any firearm. in my observation over many years most .308 guns have recoil effect of between 7-15 foot pounds of free recoil energy.
Almost all- but the amount of recoil varies a lot. A .22 rifle has almost no recoil, a 12 gauge shotgun a lot.
stingers are Airsoft guns
Yes.
The diameter of the projectile.
Probably not. as guns become smaller and lighter, the accuracy decreases, and recoil increases.
