Mercury sport STR Sport Red, cal. 6.5 Creedmoor

The repeating rifle STR Sport is a long-range rifle designed for precision target shooting (PRS Competition). The rifle features a TLD system, crafted for precise shots at the longest distances. The massive barrel has a diameter of 22 mm at the muzzle and a length of 660 mm. The bolt is equipped with an interchangeable tactical chamber handle and an external magazine release lever, which is particularly suitable for the fast pace of competitions. The modular tactical stock is equipped with an aluminum chassis, a new forend, and a stock machined from a high-strength Egal 55 alloy on CNC machines. The cheek rest as well as the trigger travel are individually and stably adjustable with screws. The extra tube attached to the underside of the buttstock fits precisely into the recess of a standard shooting rest, thus guaranteeing additional stability. The rigid chassis made of an aluminum alloy gives the STR Sport superior precision. The multi-radial barrel profile (MRR) When comparing a traditional barrel with a polygonal and the multi-radial one, the latter is ideal for both traditional and full metal jacket bullets. In multi-radial barrels, two different radii alternate, giving the bullet geometrically positive support without overstressing it. In fact, the bullets follow the circumference pressure-formed and are not cut as in the traditional barrel, which extends the lifespan of the barrel. Furthermore, there are no sharp corners like in other barrel systems where residues can accumulate, keeping the barrel cleaner and reducing wear. All tests conducted show: Multi-radial barrels shoot better and more precisely with conventional lead bullets and with full metal jacket bullets in calibers 7.62 mm (.308) and 6.5 mm (.264) than traditionally shaped ones. At standard pressure values, the exit velocity is higher than that of the conventional barrel under certain circumstances by up to 12%. The bullet seals the bore better, preventing gas from escaping forward, which optimizes the effect of the driving energy. Additionally, the friction between the bullet and the barrel is minimized. The spatial arrangement has further improved due to the extremely tight production tolerances that must be adhered to in the manufacture of multi-radial barrels. The multi-radial barrel is ideally suited for the cold forging process. The consistency of the produced barrel profile is excellent, and the overall quality of the barrels has improved. The special barrel geometry of the barrel base in multi-radial barrels allows for a more precise and continuous guidance of the bullet through the chamber neck and the bullet bore than is the case with conventional barrel systems—the bullet strikes the barrel's rifling in the best way, reducing flight wear. Under the same conditions, less copper deposition occurs inside the multi-radial barrel, resulting in less cleaning being required. And when cleaning is necessary, it is easier than with conventional barrels. The user can further enhance the performance of the multi-radial barrel simply by applying abrasive paste, without having to worry about ruining the barrel, as can be the case with traditional profiles.
