Catering to those interested in more technical exterior ballistics data and information, Sierra launched the new web site: www.exteriorballistics.com on June 15. 2003. Technical information from both the 4th and 5th Edition reloading manuals as well as the entire Exterior Ballistics tables from the 4th manual are present on the site. A question and answer message board will keep you informed and entertained. Technical articles from Sierra Ballistic Experts Ted Almgren and Bill McDonald as well as the Sierra Ballistic Technicians will appear periodically.
