This is a list of firearm cartridges which have bullets in the 5.00 to 5.99 mm (0.197 to 0.236 in) caliber range. Length refers to the cartridge case length. OAL refers to the overall length of the cartridge.
SMc cartridges were developed in an attempt to produce an efficient cartridge combining low recoil, low heat, and high velocity. [4] The 5 mm/35 SMc has produced velocities in excess of 4,800 ft/s (1,500 m/s) shooting a 30-grain (1.9 g) molybdenum disulfide-coated Berger bullet from a 28-inch (71 cm) Pac-Nor barrel, far higher than its commercial counterpart the .204 Ruger.
Westley Richards offered solid, soft-point or the revolutionary LT-capped [note 1] bullets in two loadings, the more common being a 250 gr (16 g) bullet with a listed speed of 2,400 ft/s (730 m/s), whilst a lighter loading firing a 180 gr (12 g) bullet at 2,700 ft/s (820 m/s) was also offered for lighter game.

.22-250 Remington: A very popular round for medium to long range small game and varmint hunting, pest control, and target shooting. The 22–250 is one of the most popular rounds for fox hunting and other pest control in Western Europe due to its flat trajectory and very good accuracy on rabbit to fox-sized pests.
A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters. [2] Chg: Propellant charge, in grains; Dia: Bullet diameter, in inches; BC: Ballistic coefficient, G1 model; L: Case length (mm)
Two years later, in 1965, Remington Arms adopted the .22-250, added "Remington" to the name and chambered their Model 700 and 40 XB match rifles for the cartridge along with a line of commercial ammunition, thus establishing its commercial specification. [6] The .22-250 was the first non-Weatherby caliber offered in the unique Weatherby Mark V ...
A bullet, while moving through its barrel, is being pushed forward by the gas expanding behind it. This gas was created following the trigger being pulled, causing the firing pin to strike the primer , which in turn ignited the solid propellant packed inside the bullet cartridge , making it combust while situated in the chamber .
The 160 gr (10 g) bullet which has a sectional density of 0.328 is similar in sectional density to a 220 gr (14 g) .308 caliber (7.62 mm) bullet. As sectional density plays a large factor in penetration, the .264 caliber (6.5 mm), though a diminutive caliber from a North American point of view, has had excellent results in the field.
