Todd Christwell Priming Tool: What It Is and Which One to Buy

You searched for the Todd Christwell priming tool because you saw it in old reloading forums or a parts list. You need to know if it is still sold, how it works, and if it fixes your current de-priming problem.

What the Todd Christwell Tool Actually Is

The Todd Christwell name refers to a specific style of de-priming tool, often confused with priming or seating tools. It is a hand-held device used to remove spent primers from brass cases. If that sounds like your bench, read up on bench priming tools next.

These tools were common in early reloading guides and older manuals. Today, most loaders use a universal hand de-priming tool or a separate bench tool for this step. The original Todd Christwell design used a simple pushing mechanism to force the primer out of the case head.

It is not a bench-mounted auto-prime system that holds a box of primers. It is a simple, single-function tool. You hold the case in one hand and push the tool with the other. It is effective but slow for large batches.

• Function: Pours fired primers out of case heads.
• Style: Hand-held, spring-loaded or push-type.
• Status: Legacy design, often replaced by modern universal tools.

If you find a vintage Todd Christwell tool, check the tip. Older tips can wear down, making them hard to seat new primers later. This is why many loaders keep it strictly for de-priming and use a fresh tool for inserting new primers.

How De-Priming Differs from Priming and Seating

Many search terms mix up de-priming and priming. They are two different steps in the reloading cycle. Confusing them leads to buying the wrong tool.

De-priming removes the old primer. Priming inserts a new primer. Seating presses the bullet into the case. The Todd Christwell tool only handles the first step. It does not prime or seat. You need a separate tool for those tasks. For the detail, see our notes on bench primer.

Understanding this distinction is critical for workflow. If you are just cleaning brass, you only need a de-priming tool. If you are building full rounds, you need a complete bench setup with a press, dies, and priming system.

1. De-prime: Remove spent primer from the case head. This is the Todd Christwell function.
2. Prime: Insert new primer into the case. This usually happens on the press.
3. Seat: Press bullet into case mouth. This happens on the press.

If you only want to clear brass for annealing or inspection, a de-priming tool is enough. If you are reloading for the range, you need to know which step your tool handles.

When You Need a De-Priming Tool

You need a de-priming tool when you are preparing used brass for reloading. It is essential if you are doing bulk work on a bench. Holding a single case in a vise and pushing out the primer is slow and fatiguing.

Real situations where it matters:

• Stripping primers from a large batch of mixed brass. A dedicated tool cuts time in half compared to manual pressing.
• Preparing cases for case-lube or annealing. Primers must be removed to prevent headspace issues during heating.
• Inspecting case heads for cracks after primer removal. You cannot see the inside of the head with a primer in.

If you only load a few rounds a month, a simple de-priming pin in a press works fine. For volume, a dedicated tool saves hours. A hand-held tool like the Todd Christwell is great for occasional use but tiring for hundreds of cases.

Myth: It Is the Best Bench Priming Tool

A common search error is treating the Todd Christwell tool as a bench auto-prime. This confusion happens because both terms involve primers and cases. The other half of this decision is manual priming consistency.

Myth: The Todd Christwell tool is a bench-mounted auto-prime that holds a box of primers.

Fact: It is a hand-held de-priming tool. It does not prime. It does not seat. It has no reservoir for new primers. It only pushes out old ones.

For bench priming, you need a tool that holds a case in a die and allows a primer to be dropped in from above or inserted by hand. This is where tools like the RCBS 9460 or Hornady Iron systems come in. They mount on the press and automate the insertion step.

Look for terms like “bench mount auto prime” or “primer pocket cleaner” for the actual priming step. Do not buy a de-priming tool thinking it will solve your priming workflow. They are opposite ends of the process.

How to Choose the Right Tool for Your Bench

Choose based on your volume and your cartridges. There is no single “best” tool for everyone. Your workflow dictates the hardware.

If you reload high volume, a bench-mounted auto-prime like the RCBS 9460 or Hornady Iron system saves time. It reduces hand fatigue and ensures consistent primer depth. Consistent depth is vital for uniform pressure in your chamber.

If you reload low volume, a universal hand de-priming tool is enough. It is cheaper and requires no bench space. Keep it in a drawer and pull it out when you have a batch of brass to clean.

Check these factors:

• Cartridge compatibility: Does it handle your longest and shortest cases? Universal tools usually cover most, but check the spec sheet.
• Primer type: Small rifle, large rifle, or pistol? Some tools are specific to one size.
• Ergonomics: Is it comfortable to hold for 100 cases in a row? Hand tools get tiring.

For most bench loaders, the Lee Precision kit is a strong middle ground. It provides the Auto-Prime and shell holders, which cover the majority of common cartridges without the premium cost of a full progressive press.
