![]() Ok for the field but not great for precision shooting. It is a MilSpec trigger with a hefty 7lb pull. In ten shots I virtually eliminated the center bull and was shooting through the hole on subsequent rounds. ![]() After one adjustment I put every follow up round dead in the bullseye. The first three rounds were touching each other at 50 yards about and inch below the bull. I bore sighted the scope and then took it to the range. The two together was considerably more expensive than others I looked at. I mated it with a 1-4 24mm Trijicon scope. I like the ergonomic inserts on the stock, grip and handle. The action and smooth operation right out of the box impressed me.

Co-60, a commercially important radioisotope, is useful as a radioactive tracer and gamma ray source. Cobalt is a ferromagnetic metal and is used primarily in the production of magnetic and high-strength superalloys. Cobalt produces brilliant blue pigments which have been used since ancient times to color paint and glass. Cobalt is found in cobaltite, erythrite, glaucodot and skutterudite ores. In its elemental form, cobalt has a lustrous gray appearance. Cobalt was first discovered by George Brandt in 1732. The cobalt atom has a radius of 125 pm and a Van der Waals radius of 192 pm. The number of electrons in each of cobalt's shells is 2, 8, 15, 2 and its electron configuration is 3d 7 4s 2. Cobalt (atomic symbol: Co, atomic number: 27) is a Block D, Group 9, Period 4 element with an atomic weight of 58.933195. Please contact us for information on lead time and pricing above.
