Two-sided loading tray with 50 slots
Frankford Arsenal 393939: a loading tray for different case diameters
The Universal Reloading Tray organizes up to 50 cases during the individual work steps. Its two-sided design and stepped cavities cover a wide range according to the manufacturer: rifle cases from .17 to .458 as well as handgun cases from 9 mm to .500 S&W.
The decisive advantage is not only the capacity. Cases of different sizes can stand stably in stepped cavities without having to keep a separate loading tray ready for each caliber.

Which side fits which case?


Top side: rifle calibers Designed for a wide range from .17 to .458 caliber.

Top side: larger handgun cases Manufacturer examples are .38 Special, .357 Magnum, .40 S&W, and .500 S&W.

Bottom side: compact handgun cases The opposite side takes 9 mm and .45 ACP according to the manufacturer.

Stepped cavities Several diameters can use the same cavity; before starting work, the more stable side is chosen.


Purchase check before ordering

You want an open workbench loading tray for up to 50 cases – not a lockable ammo box.
Your cases fall within the ranges specified by the manufacturer and stand stably on one of the two sides.
You don’t need a caliber-specific fit where each cavity is made exactly for one case geometry.
You don’t expect a measuring function: The tray is neither a cartridge gauge nor a case length or headspace gauge.


Why a univers
elles Ladebrett sinnvoll sein kann
Who loads multiple calibers quickly loses track and workspace with many caliber-specific blocks. The 393939 combines a wide range of uses in one component. It is especially suitable for sorted batches, visual inspections, and workflows where the cases should stand upright and in a traceable order.
Universal does not mean unlimited, though. Case shape, base diameter, and center of gravity differ. Therefore, check with a single empty case which side of the tray offers more stable guidance before using the entire batch.

Practical tip: Make the order visible
Reserve rows or clearly separated areas for each processing stage. Don’t casually turn a case over or mix already inspected cases with those not yet checked. A simple, consistent arrangement prevents errors more than additional speed.

Sensible workflow

Place the loading tray on a clean, flat, and vibration-free work surface.
Check with an empty case which side and step provide a secure stand without jamming.
Only work on one clearly marked caliber or batch at a time if there is a risk of confusion.
Insert cases evenly and set aside damaged, conspicuous, or unstable examples separately.
After each step, check the number and orientation before passing the batch on.
Empty the tray after use and clean off residues; do not store loose components uncontrolled inside.


Clear limits against bad purchases
The Universal Reloading Tray has no lid and no individual locking. It is not intended as a transport container. The wide caliber range is a manufacturer approval for the holding geometry, not a statement that every conceivable special case fits equally firmly. Never press non-fitting cases into a holder.

Scope of delivery
Included is a blue Frankford Arsenal Universal Reloading Tray, model 393939, with double-sided, stepped holders and a total capacity of 50 cases. Cases, tools, reloading press, and other reloading components are not part of the described scope of delivery.
Universal tray or caliber-specific block?
The universal tray is the flexible solution for changing cases. A caliber-specific block can be better if you always work with the same caliber and expect maximum lateral guidance. For a mixed workshop, the 393939 is the pragmatic all-rounder; for special cases, the actual fit should be checked before fully loading.
You can find more products from the manufacturer in the FRANKFORD ARSENAL collection. Reloading presses, case processing, and complementary tools are bundled in the Reloading section.
FAQ about the Universal Reloading Tray 393939
How many cases fit in the loading tray? The manufacturer’s stated capacity is 50 cases.
Which rifle calibers are supported? Frankford Arsenal specifies a range from .17 to .458 caliber for the top side. Special shapes should be individually checked for stable fit before fully loading.
Which handgun cases fit? Examples for the top side given by the manufacturer are .38 Special, .357 Magnum, .40 S&W, and .500 S&W. The underside is intended for 9 mm and .45 ACP.
Why does the tray have two sides? The sides accommodate different case diameters. By flipping it, you can use the holder that fits the respective caliber better.
Can I use different calibers at the same time? The geometry can hold several sizes. For a safe reloading process, however, different calibers and batches should be clearly separated to avoid confusion.
Is the loading tray also a cartridge gauge? No. It holds cases upright but does not check cartridge chamber dimensions, case length, headspace, or finished
Cartridge dimensions.
Is it suitable for transporting loaded ammunition? No. The open board has no lid and no transport lock. A suitable, lockable ammunition box is required for that.

Black-Raptor classification: The 393939 is interesting for reloaders who organize several common rifle and handgun calibers on the same workbench. Its strength is flexibility; its limit is the deliberately non-caliber-specific fit.
