Description
The Lee Pro 6000 Six Pack Shell Plate #4S is the part that holds your brass in each station as the press cycles, and getting the right one matters just as much as the dies you run. This is the size 4S plate, machined from steel and made specifically for the Lee Pro 6000 Six Pack progressive press. It covers one of the busiest case groups a reloader will ever touch, so if you're loading plain-base small rifle or the little .380 pistol, this is likely the plate you've been looking for.
What the #4S Shell Plate Handles
According to Lee Precision, the #4S plate works with 22 Nosler, 222 Remington, 223 Remington, 380 ACP, and 300 AAC Blackout. That makes it a strong pick for anyone feeding an AR-15 with .223 or building subsonic 300 Blackout, while still doing double duty for pocket pistol .380 loads. One plate, several of the most common cartridges people actually run, which is part of why it stays in and out of stock so often.
Fit and Build on the Pro 6000 Six Pack
This is a direct-fit accessory for the Pro 6000 Six Pack system, so there's no guesswork once you have the correct size. The plate indexes your cases through all six stations, holding the rim square so sizing, priming, charging, and seating all line up the way they should. The steel construction is built to take the repeated cycling that comes with a progressive setup, and a clean, properly fitted shell plate is one of the quiet secrets to smooth feeding and consistent rounds.
Keep in mind the shell plate is sized by case head and rim dimensions, not strictly by caliber name, which is why a single plate covers cartridges that look pretty different on paper. If you're running more than one of the calibers listed above, this one plate has you covered without buying extras. Match your cartridge to the 4S size, thread it onto your Pro 6000, and get back to loading.

Frequently Asked Questions
What cartridges does the #4S shell plate work with?
Per Lee Precision, the #4S plate is set up for 22 Nosler, 222 Remington, 223 Remington, 380 ACP, and 300 AAC Blackout. Shell plates are sized by rim and case head dimensions, so a single plate can cover cartridges that look very different on the outside. If your round is on that list, this is the plate you need.
Does this shell plate fit the Lee Pro 6000 Six Pack press?
Yes. This is a direct-fit accessory made specifically for the Lee Pro 6000 Six Pack progressive press. It is not a conversion part for older Lee presses, so make sure your press is the Pro 6000 Six Pack before ordering.
Can I use this one plate for both .223 and .380 ACP?
You can. The #4S covers both of those calibers along with the others in its group, so if you load both you only need this single plate. You will still want the correct dies for each caliber, but the shell plate itself carries over.
Is the shell plate made of steel?
Yes, the Pro 6000 Six Pack shell plates are machined from steel, which holds up to the repeated indexing and pressure of progressive reloading. A clean, properly sized plate helps your cases feed square through all six stations for more consistent rounds.
