Vinyl microgroove phonograph records typically yield 55-65 dB, though the first play of the higher-fidelity outer rings can achieve a dynamic range of 70 dB. [25] German magnetic tape in 1941 was reported to have had a dynamic range of 60 dB, [26] though modern-day restoration experts of such tapes note 45-50 dB as the observed dynamic range. [27]
Trumbull chose 70 mm film for his new process, to provide higher resolution. He also did research into frame rate , running a series of tests with 35 mm stock filmed and projected at various speeds, shown to audiences who were instrumented to biometrically test their responses.
An LP made out of perfect vinyl would have a theoretical dynamic range of 70 dB, [6] though measurements indicate actual performance in the 60 to 70 dB range. [7] [failed verification] Compare this to digital recording. Typically, a 16-bit digital recording has a dynamic range of between 90 and 95 dB. [8]: 132
Typical values for the PSNR in lossy image and video compression are between 30 and 50 dB, provided the bit depth is 8 bits, where higher is better. The processing quality of 12-bit images is considered high when the PSNR value is 60 dB or higher. [3] [4] For 16-bit data typical values for the PSNR are between 60 and 80 dB.
Note that each category will include weapons that are in that general size class. Weapons of similar caliber may differ in exact caliber (i.e. 76 mm and 76.2 mm will both be under 76 mm artillery). Non metric calibers are placed within the nearest calculated metric category.

.950 JDJ cases are approximately 70 mm in length, and are based on a 20×102mm Vulcan case shortened and necked up to accept the .950 in (24.1 mm) bullet. Projectiles are custom-made and most commonly weigh 3,600 grains (230 g) which is 8.2 ounces or over half a pound.
The .338 Lapua Magnum (8.6×70mm or 8.58×70mm) is a Finnish rimless, bottlenecked, centerfire rifle cartridge. It was developed during the 1980s as a high-powered, long-range cartridge for military snipers. Due to its use in the War in Afghanistan and the Iraq War, the cartridge has become widely available.
