RCBS Lock-Out Die Helps Prevent Faulty Charges on Progressives

RCBS Lock-out dieIf you load pistol or rifle ammo with a progressive press, we strongly recommend you get a Lock-Out Die from RCBS. This unique reloading die will prevent your progressive press from advancing if the dispensed powder charge is more or less than about 0.3 grains too high or too low. The Lock-Out Die really works. Your Editor uses it on his RCBS 2000 progressive press. I can affirm that a Lock-Out Die has “saved my bacon” a half-dozen times over the years when there was an over-charge (which could cause a Kaboom) or a low charge (which could cause a squib load).

The Lock-Out Die works by using a central die detection rod that sets its vertical position based on the height of the powder column in the case. Through an ingenious design, if the powder column height is too low or too high, the rod locks in place as you start to pull the press handle. This halts the press before the ram can lift and the cartridge plate can advance. Unlike a beeping alarm system (which can be ignored or defeated), the Lock-Out Die physically stops the movement of the press ram and prevents a bullet being seated in the “problem” case.

RCBS Lock-out dieIt takes a bit of tweaking to get the Lock-Out Die detection rod setting just right, but once it is correctly positioned, the Lock-Out Die works smoothly in the background. The Lock-Out Die won’t interfere with the loading process unless it detects a high or low charge — and then it positively stops the progressive loading cycle.

While crafted for use in RCBS progressive presses, the RCBS Lock-Out Die can also be used on a Dillon XL Progressive (see video below) or Hornady Lock-N-Load progressive — though it does take up one station which could otherwise be used for a final crimp die (after the seating die). The RCBS 2000 has one more station than a Dillon 550/650, so it’s an ideal platform for using the Lock-Out Die.

Part One explains how the Lock-Out Die functions, using cut-away illustrations. Part Two shows how to install and adjust the Lock-Out Die on various progressive presses. The video below shows setup of the RCBS Lock-Out Die on the Dillon XL-650 progressive press.

Progressive Presses — Video Showcase of Six Machines

ultimate reloading progressive press review dillon Mark 7 rcbs lee hornady

COVID-19 stay-at-home orders have created abundant free time at home for millions of Americans. To fill otherwise empty hours, we know many readers have been reloading ammo — LOTS of ammo. And quite a few of you folks are thinking of getting a progressive press to increase output. Because multiple operations take place with a single pull of a lever, a progressive press can produce way more ammo in a given period of time than any single stage press. With a progressive, on the ram up-stroke, the multiple stations can simultaneously remove spent primer, full-length size case, drop powder, seat bullet, and crimp (if desired). Most progressives are also set up to prime cases with the ram in the lower position — though some guys prefer to prime manually.

Progressive presses aren’t just for high-output pistol ammo or bulk rifle ammunition. Good progressives can be adapted to do certain reloading tasks for top-on-the line match ammo. You might use a progressive for decapping, priming, and sizing, then throw powder and/or seat bullets separately. Some Champion shooters do use progressives to load their match ammo! For example 5-Time National Long Range Champion John Whidden and 2020 Berger SWN F-Open Champion Jay Christopherson both use progessive presses for some (but not all) operations.

To help you get started with progressive presses, here are five videos from UltimateReloader.com that cover six popular machines, from the elite Mark 7 Evolution to the inexpensive Lee Pro 1000. With many of these machines you can add separate vertical bullet feeder systems that further increase loading efficiency.

Better Safe Than Sorry — the RCBS Lock-Out Die
RCBS Makes a “Lock-Out Die” that senses the powder charge. This will halt the Progressive press if you have a double charge, or an undercharge. Your Editor has the Lock-Out Die on his RCBS Pro 2000. It has “saved his bacon” a half-dozen times over the years. It can be used on Dillon and Hornady progressives as well as RCBS machines.
