January 21st 2023. Looking for some winter reading material? Sierra Bullets offers a wealth of information for free. These links will take you to more than 60 articles that provide information about bullets, ballistic coefficients and wind drift. They also include up/down angles, temperature effects and tailwind effects. These resources are mainly from the Sierra Reloading Manuals 4th and 5th editions. There are enough articles to keep you busy for a year. Major Ballistics Reference Articles
