The Cartridge 308 Winchester<\/strong> is ideally suited for silencers - reloaders in particular can optimise a lot of performance here<\/p>\n<\/blockquote>\n

Translate excerpts from the original USA page - English report HERE<\/a><\/strong><\/p>\n

Good silencers (SD)<\/a><\/strong> unfortunately lengthen the long gun and, in the case of higher silencer weight<\/strong>and also the point of impact by changing the barrel oscillation. Some Overbarrel silencer<\/strong> are also only a compromise - they only create a little more air volume<\/strong> - but no internal construction in the overbarell area.<\/p>\n

The best effect is achieved with special SD interior<\/strong> about the Total silencer length<\/strong> achieved. However, if you want to stay SHORT with the gun, this is only possible with a short barrel. The 308 Winchester cartridge<\/strong> is the ideal solution here.<\/p>\n

It is designed for short runs, has a Enormous power in relation to the size <\/strong>and as a rule (except for long runs) a Fast-burning powder<\/strong> (very High degree of powder conversion<\/strong> in gas of as good as 100%). One 30-06 with short barrel<\/strong> is probably a pity for the expensive, progressive powder, as too much of it burns outside the barrel (or in the silencer).<\/p>\n\n\t\tKinetic energy online calculator HERE<\/span>\n\t<\/a>\n\n\n\n\t\tCalculate flight curve yourself HERE<\/span>\n\t<\/a>\n\n\n

Conclusion for the reloader: In practice, this means that Shooting with 308 Win. from short barrels is possible without loss of performance<\/strong> possible. The use of coordinated labours with offensive burning NC powder<\/strong>With a special bullet weight, adapted bullet weight and powerful primers, short barrels between 420 and 560 mm are possible without any problems.<\/p>\n<\/blockquote>\n
