For example, because Pyrodex, a common black powder substitute, is less dense than black powder, a measurement by weight on a scale of 60 grains of mass of Pyrodex would be near a 30 percent overload. Volume equivalence is a benefit in loading muzzleloading firearms, traditionally loaded using volumetric measures.
This is the equivalent of +P loading as normal pressure for the .45 Colt is 14,000 psi (97 MPa). [11] In a section specifically titled "45 Colt for Ruger or Contender only" Speer makes reference to velocities up to 1,300 ft/s (400 m/s) with 200 gr (13 g) bullets. They also state that pressures do not exceed 25,000 psi (170 MPa) (CUP).
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point.. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name.
The .45 BPM uses the .460 S&W Magnum brass casing as its container. The .460 S&W Magnum was derived from the .454 Casull while the .454 Casull was derived from the .45 Colt. Because of this lineage the .460 S&W Magnum has similar dimensional attributes to the .45 Colt with the exception of a much longer casing.
The .450/400 Black Powder Express cartridges served as the parent cases for the .450/400 Nitro Express cartridges, the same cartridge cases loaded with greater loads of cordite and heavier bullets to produce far more powerful rounds. [1] [2]
The .45-90 Express is a modern adaptation of .45-90 Sharps which uses the same 2.4 inch case, but uses smokeless powder loaded to pressures up to 45,000 psi. With a 26-inch barrel the .45-90 Express is capable of over 4,200 ft-lbs (5694 J) muzzle energy.
Hodgdon's product line includes Pyrodex and Triple Seven, which are modern substitutes for black powder and intended for use in muzzleloaders and certain antique firearms. Consequences of black powder's easy ignition by sparks or static electricity make manufacture and storage hazardous. The sole factory of the United States' largest 20th ...
Consequently, firearms that fire .460 S&W are usually capable of firing the less powerful .454 Casull, .45 Colt, and .45 Schofield rounds, but this must be verified with each firearm's manufacturer (most lever-action firearms can only feed cartridges within a certain overall length and bullet profile range). The reverse, however, does not apply ...
