A method for making an improved projectile 360, 460 by defining a discontinuity, groove or trough in a distal ogive section of the projectile to provide an external ballistic effect uniforming surface feature (e.g., nose ring groove 369, 469) which makes an unsupported gap in the ogive profile that beneficially affects the flow of air over the front half of the ogive. The improved bullet's external surface discontinuity feature (369 or 469) creates effects in the flowfield that dominate any dynamic effects from bullet-to-bullet manufacturing inconsistency and resultant differences in dynamic behavior.
A ballistically enhanced projectile 360, 460 includes a body having a distal ogive section with external ballistic effect uniforming surface discontinuity (e.g., nose ring groove 369, 469) defined therein to provide an unsupported gap in the ogive profile which affects the flow of air over the front half of the ogive to provide greater aerodynamic uniformity and shot-to-shot consistency with more uniform observed external ballistics and superior terminal ballistics. The bullet's external surface discontinuity feature (369 or 469) creates effects in the flowfield that dominate any dynamic effects from bullet-to-bullet manufacturing inconsistency and resultant differences in dynamic behavior.

A rifle or portable firearm assembly (e.g., 310) configured to work with user-actuable sensors and systems (e.g., S1-S4), comprises a removable receiver assembly 312 attached to and responsive to a trigger assembly 50 which are removably received in a stock or chassis 316 having a middle section 324 with a trigger motion sensing sidewall segment with at least one trigger motion sensor (e.g., 340L, 340R) which does not physically contact or attach to the trigger assembly and is instead spaced from every component of the trigger assembly when the receiver is installed in said stock or chassis. The trigger motion sensor is configured to sense, from a selected standoff distance, without contacting or interfering the trigger assembly in any way, at least one of (a) the trigger's first stage movement or (b) actuation of a safety lever, and generate a “trigger motion sensed” signal in response thereto.

A drop-in adjustable trigger assembly has a camming safety linkage to selectively move and engage a bolt sear to positively prevent movement of the bolt sear. The drop-in trigger assembly housing carries a pivoting bolt sear engagement member which is connected to a sear safety linkage. The housing has a sear safety linkage slot defined therein which guides the pivoting sear safety linkage in response to actuation of an upwardly projecting thumb safety lever's actuation. A trigger bracket preferably carries a removable, reversible trigger shoe and is configured to pivot within the housing about a pivot point within the housing, and the trigger bracket carries an adjustable rocker having (preferably) a first stage movement adjustment and a second stage length adjustment. The pivoting safety mechanism's safety linkage pivots rearwardly to push upon or cam the bolt sear upwardly, thus disengaging the bolt sear from the trigger sear.

The multiple nomograph system for solving ranging and ballistic problems in firearms includes a series of graphs or nomographs for the determination of a series of factors affecting the ballistic trajectory of a bullet in flight. The nomographs may be placed upon the reticle of a firearm scope, or provided on media external to the scope, as desired. The scope reticle includes at least one aiming point or aim point field to compensate for elevation and windage, with the vertical axis preferably being offset to compensate for precession at longer ranges. Stadia for determining angular target dimension(s) are included on the reticle, with a nomograph for determining apparent distance from the apparent dimensions being provided either on the reticle or external to the scope. Additional nomographs are provided for the determination and compensation of non-level slopes, non-standard density altitudes, and wind correction, either on the reticle or external thereto.
