.50 Alaskan

The .50 Alaskan is a wildcat cartridge developed by Harold Johnson and Harold Fuller of the Kenai Peninsula of Alaska in the 1950s. Johnson based the cartridge on the .348 Winchester in order to create a rifle capable of handling the large bears in Alaska.

Design

Harold Johnson necked out the .348 Winchester case to accept a .510" diameter bullet, and Harold Fuller developed the barrel, marrying a .50 caliber barrel to an old Winchester Model 1886 rifle.

Since the rifle was designed for use on Alaska’s great bears, Johnson cut 720-grain (47 g) boat-tail .50 BMG bullets in half, seating the 450-grain (29 g) rear half upside down in the fireformed .50-caliber case. It didn’t take Johnson long to find out that the 450-grain truncated shaped "solid" would shoot through a big brown bear from any direction, claiming in 1988, "I never recovered a slug from a bear or moose, no matter what angle the animal was shot at."

Performance

Harold’s favorite load in the .50 Alaskan was 51.5 grains (3.34 g) of IMR-4198 with a Barnes 400-grain (26 g) flatnose, jacketed bullet for about 2,100 ft/s (640 m/s) and just under 4,000 ft·lbf (5,400 J)of muzzle energy..

Diamond

In mineralogy, diamond (/ˈdaɪəmənd/ or /ˈdaɪmənd/; from the ancient Greek ἀδάμας – adámas "unbreakable") is a metastable allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. Diamond is less stable than graphite, but the conversion rate from diamond to graphite is negligible at standard conditions. Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. In particular, diamond has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools and the scientific applications in diamond knives and diamond anvil cells.

Because of its extremely rigid lattice, it can be contaminated by very few types of impurities, such as boron and nitrogen. Small amounts of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (lattice defects), green (radiation exposure), purple, pink, orange or red. Diamond also has relatively high optical dispersion (ability to disperse light of different colors).

The limited edition includes a 52-page photobook that highlights some of their single releases and Japanese debuts. The album sold 7,060 copies in Japan, peaking at the #27 spot in the Oricon weekly charts. The Korean edition of the album was released in January 25, 2011, but doesn't includes the Korean songs from their debut EP "For Muzik".

Singles

The first single from the album (and also their Japanese debut single) is a Japanese version of the song "Muzik". It was released on May 5, 2010 and included Japanese versions of the Korean hits "Muzik" and "Hot Issue", as well as the Korean version of "Muzik". It ranked at number 12 in Oricon's Daily Singles chart., 21 in the weekly chart,, and sold 8,234 copies. The music video for the song shows the members in a blue room with flashing lights, along with scenes filmed in a red room. It also takes one of the Korean scenes where the members are together wearing the latex leggings.
