Dillon 650/1050 Powder Check system is a warning system that will alert you with a load beep in case your powder charge is off, either too low or too high.
When calibrated and adjusted on your tool head this simple, clever device will sound an alarm if the level of power in your case is not what it should be. This is immensely helpful in preventing squib loads or accidental double-charges.
A small, relatively inexpensive accessory that can prevent a serious accident leading to destroying your expensive firearm and/or serious injury.
Fits the XL650 and RL1050/Super 1050 machines.
