Saturday at the Movies: Seven Progressive Presses in Review

With the high cost and reduced availability of factory ammo, more shooters are loading their own ammo. When good 9mm pistol ammo was $10/box, it might be hard to justify handloading. Now that 50 rounds of factory 9mm can run $25 or more it certainly makes sense to reload. The same is true with rifle ammo if you shoot large quantities, or if you simply can’t find your preferred ammo for sale these days.

To increase productivity when reloading large quantities of ammunition, many shooters are thinking of getting a progressive press. 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 six videos from UltimateReloader.com that cover seven popular machines, from the elite Mark 7 Evolution to the affordable Lee Loadmaster. With many of these machines you can add separate vertical bullet feeder systems that further increase loading efficiency. Machines Covered: Lyman Mark 7, Dillon XL-650, Dillon XL-750, Dillon RL-550c, RCBS Pro Chucker 7, Hornady Lock-N-Load AP, and Lee Load Master.

The RCBS Lock-Out Die can also be used with some Dillon and Hornady progressive presses.

If 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.

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.

It 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 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). This Editor has used the RCBS Lock-out die very successfully on an RCBS 2000 progressive press for many years.
