Welcome to the forum. Your story sounds like mine. Semper Fi!
Yes, most of the manuals will cover the process, but generically. Basically, you are removing the old primer and resizing the brass (it expands after firing) so that it will feed reliably and hold a new bullet. Then you reprime, add powder, and cap off with a bullet. The key to accuracy and safety in that is consistency, choosing the appropriate components for the use, consistency, measuring the components to the specs of your rifle, and consistency.
One of the most common causes of malfunction is not sizing properly. You won't be able to tell by merely looking, but not pushing the cartridge's shoulder back far enough will result in a stoppage.
One of the most common causes of catastrophic failure is using the wrong powder, or too much of it. Pistol powder will destroy a rifle. On the other hand, too little powder (ie, forgetting to add it) may result in a squib. If you perform immediate action and shoot again with a bullet stuck in your bore, you will be buying a new rifle and probably getting checked out at the doctor.
Both of these are easily preventable by methodically working through the loading procedure and paying attention to what you are doing. It is a rewarding endeavor but will not save you a bit of money because you will find yourself shooting more often.
