This makes the 7mm Remington Short Action Ultra Magnum better suited for loading long heavier bullets. These 21st-century ballistic twin short fat magnum cartridges can handle 440.00 MPa (63,817 psi) P max piezo pressure according to the C.I.P. or a maximum average pressure of 65,000 psi (448.16 MPa) piezo pressure according to the SAAMI.
Source(s): Accurate Powder [2] The 7mm Shooting Times Westerner , sometimes referred to as the 7mm STW , began as a wildcat rifle cartridge developed by Layne Simpson, Field Editor of Shooting Times, in 1979. [ 3 ]
The resulting case has significantly more capacity than any conventional belted magnum. Compared to the 7mm Remington Magnum , top 7mm RUM loads deliver 25% more energy at 300 yards. [ citation needed ] Such performance demands a price and in this case, that is a large muzzle blast, sharp recoil and short barrel life.
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.
These are both more energetic by mass than black powder and can produce higher velocities and pressures. Triple Seven is a volumetric substitute for black powder, and due to its higher velocity, it is recommended to reduce the load by 15%. [11] The carbon-based fuel burned in this case is from the sugar family, not from charcoal.

Magnum pistol cartridges reverse this power/accuracy tradeoff by using lower-density, slower-burning powders that give high load density and a broad pressure curve. The downside is the increased recoil and muzzle blast from the high powder mass, and high muzzle pressure. Most rifle cartridges have a high load density with the appropriate powders.
Remington introduced the 7mm Short Action Ultra Magnum (SAUM) cartridge in 2002 to compete with the 7mm Winchester Short Magnum cartridge. It was designed specifically for the Remington Model Seven Magnum rifle, and intended primarily for long-range hunting use. The difference in velocity between the 7mm SAUM cartridge and the 7mm Winchester ...
