Intro to Reloading
Intro to Reloading This introductory manual will cover the basics of handloading ammunition. It will include information regarding necessary equipment, required materials, and the reloading process. This is not intended to be a comprehensive guide. Reloading is an in-depth, complex subject. This guide is a starting point for absolute beginners. Further information should be sought out for your specific calibers you are reloading, your specific brand and models of equipment, and your specific reloading components and materials. Follow all instructions that come with your equipment and materials. When someone who has never reloaded their own ammo looks into it, the needed equipment list is daunting and expensive. It is the intention of this guide to make reloading seem easy and accessible. Anyone, even children, can reload ammunition if shown the steps. My 8 year old is more than eager to help me de-prime, drop powder, or resize shells. Hopefully the knowledge presented here will increase your confidence when it comes to starting your reloading journey. [2] Socialistra.org Why Reload? Self Sufficiency: A decade ago, the generally accepted wisdom was “You will always be able to find .22lr. You will always be able to find .223. You will always be able to find .30-06. You will always be able to find XYZ.” After Sandy Hook in 2012, that all changed. For YEARS afterward, certain kinds of ammo were simply non-existent on store shelves. In this Time of Trump, it may not seem to make sense to spend $.10-$.25 more on each round you would make vs just buying the factory ammo. -
