The 28 Nosler is a 7mm (.284”) caliber, rebated-rim centerfire rifle cartridge designed by Nosler. Introduced in 2015 and approved by SAAMI on January 19, 2015, the 28 Nosler is based on the 26 Nosler which was released in 2014. The 28 Nosler shares the same overall cartridge length (3.340”) as the 26 Nosler which allows it to be chambered in standard-length action.〔(【引用サイトリンク】url=http://www.americanhunter.org/blogs/28-nosler )〕 This feature helps weight-conscious sportsmen to lighten their load before venturing into the backcountry. The cases’ overall length also aid in quick follow-up shots, since the bolt throw is shorter than on a magnum action.〔(【引用サイトリンク】url=http://www.gundigest.com/ammunition-reviews-articles/reloading-handloading-articles-advice/pushing-the-limits-with-the-28-nosler )〕 The name 28 Nosler refers to the first two digits in the caliber (0.284”) of the bullets that the cartridge fires and the name of the company which created it. The 28 Nosler cartridge case can be formed by “necking-up” or expanding the neck of a 26 Nosler case to 7mm (.284”) diameter. The cartridge case for both the 26 and 28 Nosler is based on the 404 Jeffrey case. == Performance == Nosler took the 6.5mm cartridge and necked it up to 7mm. The 28 Nosler is loaded in a variety of weights.〔(【引用サイトリンク】url=http://www.fieldandstream.com/blogs/the-gun-nuts/new-long-range-rifle-load-2015-28-nosler )〕 According to data listed for Nosler ammunition, the 28 Nosler is capable of firing a 160 gr. AccuBond® bullet at 3300 fps muzzle velocity or a 175gr AccuBond® Long Range bullet at 3125 fps muzzle velocity when fired from a rifle with a 26” barrel.〔(【引用サイトリンク】url=http://www.28nosler.com/ )〕 To give some context, at 160 grains the 28 Nosler is around 300 fps faster at the muzzle than the 7mm Remington Magnum. 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「.28 Nosler」の詳細全文を読む スポンサード リンク
