Description
If you run a Lee Auto Breech Lock Pro or Pro 4000 progressive press, the shell plate is the heart of the whole operation, and the #2 is the one you want for the big-bore pistol rounds. This is the plate sized to hold .45 ACP and .45 GAP brass, keeping each case locked in place and rotating cleanly through every station as you work the handle. Lee machines these from steel and precision grinds them, which cuts down on the snags and rough edges that slow a loading session to a crawl.
What the #2 Shell Plate Handles
The #2 covers the .45 ACP and .45 GAP family, which makes it the go-to plate for anyone loading up range quantities of the venerable .45 Auto. Because it shares a rim size with several other cartridges, some loaders also run it with cases like .308 Win and 30-06 that fall into the same group, though it's primarily marketed around the .45 handgun calibers. If your main goal is cranking out .45 ACP, this is the plate that belongs on the press.
Fit Notes for Your Lee Auto Breech Lock Pro
Worth knowing up front: the Auto Breech Lock Pro and Pro 4000 use their own dedicated shell plates. These will not interchange with Lee's other presses like the Pro 1000 or the Classic Turret, so you want to confirm you're grabbing the Breech Lock Pro style plate, which this is. Swapping it in is a quick job, drop it into position and screw it down, and you're set for a caliber change.
Why a Clean Plate Matters on a Progressive
On a progressive press, every pull of the handle finishes a round while advancing the others toward completion, so the shell plate is doing real work on each stroke. A properly ground, correctly sized plate keeps that rhythm smooth and your case indexing consistent. Keep it wiped down and lightly lubricated and this plate will see you through plenty of loading sessions.

Frequently Asked Questions
Which presses does the Lee Shell Plate #2 fit?
It's made for the Lee Auto Breech Lock Pro and the Pro 4000 progressive presses. These presses use their own dedicated shell plates and will not accept plates from other Lee presses, so this one is specific to that platform. Drop it in, screw it down, and you're ready to load.
What cartridges does the #2 shell plate work with?
The #2 is sized for .45 ACP and .45 GAP, making it the standard choice for loading .45 Auto on your Breech Lock Pro. It shares a rim group with some other cartridges, but its main calling is the .45 handgun rounds. If .45 ACP is your focus, this is the right plate.
Can I use my regular Lee shell holders with this plate?
No, shell plates and shell holders are two different things. A shell holder is for single stage and turret work, while this shell plate is the rotating component that indexes multiple cases through the stations on a progressive press. You'll need this specific Breech Lock Pro plate rather than a standard shell holder.
Is the Lee Shell Plate #2 made of steel?
Yes, it's machined from steel and precision ground. That grinding helps prevent cases from snagging or hanging up as they index, which keeps a loading session running smoothly. A quick wipe-down and light lube now and then will keep it working well for the long haul.
