Everyone knows that reloading is a very rewarding experience. Especially having the ability to pick the kinds of ammo you wish to create, you also do it relatively cheaply, more than 1/4 of the price of the cheapest factory ammo you’d buy in retail.
While rewarding, it doesn’t come without any risks. One of the biggest problems with reloading is with the user. Humans are not good at repetitive actions, we tend to get used to the repetition and lose our concentration. That can lead to disastrous problems with the ammo you’re reloading, especially if you double charge your load.
This problem can be negated by checking every load for the right amount of powder, and the best way to do it is to physically look into the case for the right amount of charge. This can be a little difficult depending on the kind of lighting conditions you’d have around your reloading workstation.
Here’s a cheap LED flashlight I bought from True Value hardware, called Coast LED Lenser. I think I bought this for $4.99. You can find one on Ebay here : http://cgi.ebay.com/NEW-Coast-Logo-Lenser-FLASHLIGHT-LED-KEYCHAIN-/190472302121?pt=LH_DefaultDomain_0&hash=item2c5908ae29

This LED Flashlight is the right size to be slipped into the Dillon RL 550 toolhead.

The light is held in place, without falling through, by the activation switch. It sits in the perfect depth that it doesn’t impinge the function of the shellplate during reloading and providing enough illumination to look into your brass cases.

Perfect! Go get one!
