Toolhead Station's
Case Feed
This is where it all begins. The cases (brass) that you’ve put in the case feeder bin drop down into the case feed assembly, are fed into the case feed ram and then inserted into the shellplate. Once the case is in the shellplate, it's carried from station to station through the reloading process.
Size Die
At the 4th station you put your sizing die with the decapping rod removed. Sizing over the priming station provides two functions. First, we are re-sizing the case, bringing once fired brass back to its proper dimensions so it can be ready for use. Second, by using a sizing die over the priming station, the case is held firmly in place allowing for ultra reliable priming. Lyman Pro Dies feature carbide inserts that ensure correct sizing and long term use. Remember, even with carbide dies, you still want to lube your cases.
Case Flare Die
Flaring refers to the operation of slightly opening the mouth of the case to allow the projectile to be properly positioned in preparation for bullet seating. This is especially important when loading flat based bullets. Non-flared case mouths can result in the projectile (bullet) being shaved/deformed when seating, or even crushing the body of the case in some instances.
Powder Drop Die
The powder drop die is what interfaces your Mark 7 Mechanical Powder Measure to the press. It is at this station we are dropping a charge of powder into the primed case.
Powder Check Alarm
The powder check alarm is a battery operated alarm that will detect gross over charges (think double charge) or gross under charges (think squib) of powder in the case. If either of these situations occur, the powder check sounds an alarm to alert you.
*NOTE: If you're running a fully automated setup, you'll need a Powder Check Sensor (#101-1038)
Bullet Drop
Here's where your Bullet Feeder interfaces to your Toolhead to drop a bullet onto the mouth of the case.
Bullet Seating Die
The seating die is what pushes the projectile to it’s proper depth inside the case. While some dies combine seating and crimping, we've learned through our considerable experience that separating these two processes leads to the best results.
Crimp Die
Bullet crimping places tension on the case mouth against the seated bullet, helping to maintain the proper seating depth under recoil. While there are dies that perform seating and crimping in one function, we recommend having these actions done separately.
