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 ...
An automatic software technique finds the sharp change from the top hold time to the beginning of the unloading. This can be found by doing a linear fit to the top hold time data. The unload data starts when the load is 1.5 times standard deviation less than the hold time load. The minimum data point is the end of the unloading data.
The delta L problem (ΔL problem) refers to certain firearm chambers and the incompatibility of some ammunition made for that chamber. ΔL is a Commission Internationale Permanente (C.I.P.) geometric dimensioning and tolerancing definition for cartridge cases that are longer than the chamber they have to fit in. "Delta L" essentially means "difference in length".
7 data bits; 1 odd parity bit; 1 stop bit; The on-time marker is the leading edge of the first start bit. IRIG J-1 timecode consists of 15 characters (150 bit times), sent once per second at a baud rate of 300 or greater: <SOH>DDD:HH:MM:SS<CR><LF> SOH is the ASCII "start of header" code, with binary value 0x01.
This liquid volume measurement method can be practically employed to about a 0.01 to 0.02 ml or 0.15 to 0.30 grains of water precision level for firearms cartridge cases. A case capacity establishment should be done by measuring several fired cases from a particular production lot and calculating their average case capacity.

P-delta is a moment found by multiplying the force due to the weight of the structure and applied axial load, P, by the first-order deflection, Δ or δ. NUMERICAL EXAMPLE OF P DELTA EFFECT ON A CALCULATOR You have a 1 meter tall rigid vertical rod that rotates on a hinge at the bottom of the rod. There is a 1 newton load on the top of the rod.
What put an end to the 9×25mm Dillon in competition was lowering of the USPSA major power factor from 175 to 165 (160 for IPSC competition) which improved the safety and effectiveness of .38 Super (and later 9x19 "Major") loads to a point that the extra rounds that would fit maximum-allowed length magazines outweighed any muzzle flip advantage ...
