Precision Reloading Field and Reference Guide

Precision Reloading Field & Reference Guide is a 10-chapter technical manual by competitive ballistician Cole Ashford, built for handloaders who want to move past basic recipes and into forensic engineering protocols. It walks through the full workflow from raw brass sorting at the bench to velocity data acquisition and group dispersion analysis on target, with the aim of achieving single-digit standard deviations and sub-0.5 MOA match loads across rifle platforms.

Inside, the guide covers vertical stringing eradication, shoulder bump and headspace calibration with comparator inserts, carbon ring remediation, powder thermal sensitivity and burn rate hierarchy, three methods for finding the lands, Satterlee velocity ladders and OCW, a forensic overpressure decision tree, and ballistic chronograph math. It also includes two complete worked match load case studies, ANSI/SAAMI Maximum Average Pressure tables, and quick-reference armorer cards.
