41xx steel is a family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum, and as a result these materials are often informally referred to as chromoly steel (common variant stylings include chrome-moly, cro-moly, CrMo, CRMO, CR-MOLY, and similar).

A free-floating barrel is a firearm design used in precision rifles, particularly match grade benchrest rifles, to accurize the weapon system. With conventional rifles, the gun barrel rests in contact with the fore-end of the gunstock , sometimes along the whole length.
Stellite alloys are a family of completely non-magnetic and corrosion-resistant cobalt alloys of various compositions that have been optimised for different uses. Stellite alloys are suited for cutting tools, an example is Stellite 100, because this alloy is quite hard, maintains a good cutting edge at high temperature, and resists hardening and annealing.
The main problem with this theory is that the stored energy due to dislocations is very low (0.1–1 J m −3) while the energy of a grain boundary is quite high (~0.5 J m −3). Calculations based on these values found that the observed nucleation rate was greater than the calculated one by some impossibly large factor (~10 50 ).
The .458 HAM'R (11.6x39mmRB) is a large bore, centerfire rifle cartridge, designed for use in AR-15 style rifles.Wilson Combat, owned by Bill Wilson (developer of .458 HAM'R), sells a .458 HAM'R chambered, AR-style firearm named the WC-12, which is between the sizes of the AR-10 and AR-15 platforms.
Chromium–vanadium steel (symbol Cr-V or CrV; 6000-series SAE steel grades, often marketed as "Boss AA" [1]) is a group of steel alloys incorporating carbon (0.50%), manganese (0.70–0.90%), silicon (0.30%), chromium (0.80–1.10%), and vanadium (0.18%).
The Wilson Quarterly is a magazine published by the Woodrow Wilson International Center for Scholars in Washington, D.C. The magazine was founded in 1976 by Peter Braestrup and James H. Billington. It is noted for its nonpartisan, non-ideological approach to current issues, with articles written from various perspectives. [1]
