Dillon Belted Magnum Powder System

Magnum rifle cartridges can require from 70 grains to well in excess of 100 grains for a single charge. Dillon's new "Belted Magnum" Powder System feature a new, maximum-capacity, steel powder bar that can dispense more than 100 grains of extruded powder.

 
The new powder system can be used with your RL550, XL650 or BL550 reloader, and is ideal for loading large-caliber, magnum rifle cartridges. This system has been tested with various extruded rifle powders and it was found that powder charge variations stayed within plus-or-minus three-tenths of a grain. 
The "Belted Magnum" Powder System is based on Dillon's SL900 Shot Dispenser, so the Maximum Charge Bar won't work in our standard powder measures – you'll need to buy the entire system. The good news is that the "Belted Magnum" Powder System has an integral drain, so it's easy to empty the hopper in order to change powder types; so, if you load several big calibers with various powders, it's easy to switch from one to another.
