Most electromagnetic waves of higher frequency than visible light ( UV and X-rays ) are blocked by absorption from electronic excitation in ozone and dioxygen ( for UV ), and by ionization of air for energies in the extreme UV and above.

Most gas masks use sealing caps over the air intake to prevent the filter from degrading before use, but the protective abilities also degrade as the filter ages or if it is exposed to moisture and heat.

Most air accident investigations are carried out by an agency of a country that is associated in some way with the accident ; for example, the Air Accidents Investigation Branch conducts accident investigations on behalf of the British Government.

Most of the on air talent moved over to this independent English language project.

Most, but not all, finger-operated designs are symmetrical in design, making them usable by both hands, while thumb-operated designs are by their nature asymmetric or “ handed ,” allowing the smallest examples to be held in the air.

Most steam tunnels have large intake fans to bring in fresh air and push the hot air out the back.

Most designs are rocket engines where the energy is provided by the beam, and is used to superheat propellant that then provides propulsion, although some obtain propulsion directly from light pressure acting on a light sail structure, and at low altitude heating air gives extra thrust.

Most of the men were also skilled with the use of guns as they would hunt and also were able to protect their families with them.

Most modern long guns are either rifles or shotguns.

Most automatic weapons are classed as long guns ( as the ammunition used is of similar type as for rifles, and the recoil of the weapon's rapid fire is better controlled with two hands ), but handgun-sized automatic weapons also exist, generally in the " submachine gun " or " machine pistol " class.

Most IFVs are resistant against heavy machine guns, artillery fragments, and small arms.

Most modern weapons of this type are called Gatling guns in reference to their driving mechanism.

Most commonly, such guns have a 5-or 6-shot capacity, hence the common names of " six-gun " or " six-shooter ".

Most engagements using guns in this size range used direct fire at enemy from 1500 to 3000 yards distant, at which ranges the residual shell velocity was correspondingly higher, as in the table-at least in the earlier stages of World War 1.

Most commonly the guns in question are personal firearms, typically handguns and long guns.

Most revolver cartridges have a rim at the base of the case that is larger than the case body is and which seats against or into the cylinder block to provide headspace control ( to keep the cartridge from moving too far forward in the cylinder chamber ) and to provide for easy extraction in guns using a claw extractor ( most double-action designs ).

Most air guns use metallic projectiles as ammunition.

Most spring piston guns are single-shot breech-loaders by nature, but multiple-shot guns have become more common in recent years.

Most guns seem to respond well to a light, repeatable grip that allows the gun to vibrate the same way from shot to shot.

Most Olympic air gun matches through the 1970s and into the 1980s were shot with spring-piston guns, often of the opposing-piston recoil-eliminating type.

Most CO < sub > 2 </ sub > guns ( e. g. Beretta Elite II ) use a disposable cylinder, a powerlet, that is purchased often pre-filled with 12 grams of pressurized carbon dioxide, although some, usually more expensive models, use larger refillable CO < sub > 2 </ sub > reservoirs like those typically used with paintball markers.

Most CO < sub > 2 </ sub > powered guns use the standard 12 gram Powerlet disposable cylinder invented by Crosman.

Most CO < sub > 2 </ sub > powered guns are relatively inexpensive, although there are still a few precision target guns on the market that use CO < sub > 2 </ sub >.

Most air guns are. 177 ( 4. 5 mm ) or. 22 ( 5. 5 mm / 5. 6 mm ), and are designed for target practice, small game hunting and field target shooting.
