The results from Rifleshooter.coms .308 barrel cut-down test are quite different than the results we recorded some years ago with a barrel chambered for the 6mmBR cartridge. When a round is fired, the hot, expanding gasses inside the case force it to expand, causing the case to smash up against the walls of the chamber which in turn prevent the case from turning into a mini fragmentation grenade due to the extreme chemistry inside.

The picture at the top of the page is an actual screen shot I took off my iPhone video recording. Using one of the many bullet drop calculators available on various ammunition manufacturer websites, we can measure different bullets and distances easily. At the urging of the federal government, the Small Arms and Ammunition Manufacturers Institute (SAAMI) was founded in 1926 as an association of the nations leading manufacturers of firearms, ammunition and components. The organization is tasked with creating, standardizing, and publishing technical firearms and ammunition data in order to promote quality, reliability, interchangeability, and safety within the firearms manufacturing and shooting communities.
