124 grain 9mm Luger Full Metal Jacketed Round Nose (FMJ RN) at a velocity of 1305 ft/s (398 m/s) 158 grain .357 Magnum Jacketed Soft Point (JSP) at a velocity of 1430 ft/s (436 m/s). This is roughly equivalent to the obsolete NIJ Level II ballistic protection level. [10] NIJ HG2 9mm Luger.44 Magnum: This armor would protect against:
In aerodynamics, the normal shock tables are a series of tabulated data listing the various properties before and after the occurrence of a normal shock wave. [1] With a given upstream Mach number , the post-shock Mach number can be calculated along with the pressure , density , temperature , and stagnation pressure ratios.
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).
The lightest published load data i can find is for Lehigh Defense 100gr "Xtreme Defense". The LD bullet is not available as finished ammunition, and I don't see anything other than blog and forum posts detailing velocities or energy using that bullet, so I don't know that it's relevant here.
Here is an example of a ballistic table for a .30 calibre Speer 169 grain (11 g) pointed boat tail match bullet, with a BC of 0.480. It assumes sights 1.5 inches (38 mm) above the bore line, and sights adjusted to result in point of aim and point of impact matching 200 yards (183 m) and 300 yards (274 m) respectively.
Handloaders have worked up safe loads using 180 gr (12 g) bullets at 1,250 ft/s (380 m/s) making it an adequate round for hunting some medium game at close distances. [ 13 ] For practical shooting competitors, the .400 Corbon makes IPSC Major Power Factor of 175 and surpasses the IDPA Enhanced Service Pistol's Power Floor of 125,000 in most ...
The stress intensity factor at the crack tip of a compact tension specimen is [4] = [() / / + / / + /] where is the applied load, is the thickness of the specimen, is the crack length, and is the effective width of the specimen being the distance between the centreline of the holes and the backface of the coupon.
