The heavier bullet produced significantly superior ballistics and could reach ranges of 3,350 yd (3,060 m), which were beyond the maximum range of the .45-70-405. While the effective range of the .45-70 on individual targets was limited to about 1,000 yd (910 m) with either load, the heavier bullet produced lethal injuries at 3,500 yards (3,200 m).
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.
A typical .30-30 factory load fires a 150-grain bullet at 2390 ft/s, while the current 7-30 factory load fires a 120-grain bullet at 2700 ft/s. Muzzle energy is just over 1900 ft-lbs for both of these loads, but the lighter weight 7 mm bullet has a higher velocity and flatter trajectory.
The .444 Marlin (10.9×57mmR) is a rifle cartridge designed in 1964 by Marlin Firearms and Remington Arms.It was designed to fill the gap left when the older .45-70 cartridge was not available in new lever-action rifles; at the time it was the largest lever-action cartridge available. [1]
According to the US Army Ordnance Department tests, the 45-70-405 was loaded to 19,000 psi, [4] while the 45-70-500 was loaded to 25,000 psi [2] The average accuracy of the Springfield Model 1873 was a circle with an average radius of 1.7 inches at 100 yards, corresponding to an ~3.4 MOA.
The .450 Marlin is a firearms cartridge designed as a modernized equivalent to the .45-70 cartridge. It was designed by a joint team of Marlin and Hornady engineers headed by Hornady's Mitch Mittelstaedt, [4] and was released in 2000, with cartridges manufactured by Hornady and rifles manufactured by Marlin, mainly the Model 1895M levergun.
Dug out my internal ballistics software and plugged in the .45-70-405 data based on the Sandy Hook trials and a .308 long range load, and got the following: The scale exagerates the slope a bit--the .45-70 is actually traveling downwards at about a 20 degree angle when it hits--but the .308 is only doing about a 3.6 degree angle.
Furthermore, the projectile's high ballistic coefficient allows the .338 Marlin Express to maintain velocity to greater distances than big bore lever cartridges such as .45-70, .444 Marlin, or even the high performance .450 Marlin. Although the heavy bullet weight of these cartridges allow them more muzzle energy, the ballistic advantage of the ...
