The D&L reticle design is another Dave Lauck development to increase field performance by tactical shooters. 5-22X NXS scopes are now available from D&L Sports Inc with this reticle design. The scopes feature 30 MM tubes, 56 MM objective lenses, and are compatible with the D&L speed turret. The reticle and its use are explained in detail in the Advanced Tactical Marksman book (from Paladin Press, phone#, 303-443-7250). In brief, the reticle design allows for ranging, windage holds, leading, and general precision shooting without M.O.A., mil-dot, or other mathematical calculations. The reticle also has selective illumination for low light shooting. Varmit hunters have also made extensive use of this reticle design.
