CCI lists the #450 in its primer catalog as “450 MAG.” with boxed part number 17.

Quick Product Facts

What Are CCI Small Rifle Magnum Primers #450?

CCI #450 primers are small rifle magnum primers intended for cartridges and loading data that specify this type of primer.

A primer is the ignition component located in the primer pocket of a centerfire cartridge case. When the cartridge is fired, the primer is struck and produces the ignition needed to start the propellant-burning process.

The important point for identifying the CCI #450 is the combination of:

• CCI — the manufacturer
• 450 — the product number
• Small Rifle — the primer size/category
• Magnum — the primer’s classification

These details matter because primers that look similar can belong to different categories and can have different characteristics.

CCI #450 vs. CCI #400

One of the most common questions about CCI primers is the difference between the #450 Small Rifle Magnum and the #400 Small Rifle.

CCI lists both products separately.

The CCI #400 is listed as a Small Rifle primer for standard loads in cases requiring small rifle primers. The CCI #450 is listed as a Small Rifle Magnum primer and is described in CCI’s primer chart as a magnum primer for ball propellants.

These products should not simply be treated as interchangeable because they share the same general primer size. Primer substitutions can affect ignition and pressure characteristics, so the applicable published loading data should always be followed.

Why Is the CCI #450 Called a Magnum Primer?

The word “magnum” identifies the primer’s classification within CCI’s product line.

It does not mean that every cartridge using a small rifle primer should use a magnum primer.

CCI specifically describes the #450 as a magnum primer for ball propellants in its primer usage chart.

The correct primer depends on the cartridge, propellant, bullet, firearm, and published load data being used.

For that reason, the safest way to identify whether a CCI #450 is appropriate for a particular application is to check reliable, current loading data from the appropriate component or ammunition manufacturer.

CCI #450 and Small Rifle Primer Size

CCI #450 belongs to the small rifle primer category.

Reloading primers are available in different sizes and classifications. Small rifle, large rifle, small pistol, large pistol, and other primer types are not simply interchangeable because their dimensions and performance characteristics can differ.

The CCI catalog separates its products into categories including:

• Small Rifle #400
• Small Rifle Magnum #450
• Small Rifle No. 41/5.56mm
• Small Rifle BR4
• Large Rifle #200
• Large Rifle Magnum #250
• Small Pistol #500
• Small Pistol Magnum #550

CCI’s current catalog lists these products separately.

CCI #450 Product Identification

Correct product identification is especially important when several CCI primers have similar names.

For the product covered on this page, the key identification information is:

Brand: CCI
Product: Small Rifle Magnum
Number: 450
Catalog designation: 450 MAG.
Boxed part number: 17

When comparing product listings, packaging, or reloading records, the #450 designation is the important identifier.

CCI #450 vs. Other CCI Small Rifle Primers

CCI offers several small rifle primer products. Knowing the differences can make product research easier.

CCI #400 Small Rifle

The CCI #400 is the company’s standard Small Rifle primer. CCI describes it as being for most standard loads in cases requiring small rifle primers.

CCI #450 Small Rifle Magnum

The #450 is the Small Rifle Magnum model. CCI’s primer chart specifically identifies it as a magnum primer for ball propellants.

CCI #41 / 5.56mm

CCI also produces the No. 41/5.56mm primer. CCI identifies this as a military small rifle primer with NATO sensitivity characteristics.

It should therefore be treated as a distinct product rather than simply another name for the #450.

CCI BR4

The BR4 is CCI’s Benchrest Small Rifle primer. CCI lists it separately from both the #400 and #450.

This distinction is useful when searching for primers because Small Rifle, Small Rifle Magnum, 5.56mm-specific, and Benchrest are separate CCI product classifications.

CCI #450 and Ball Propellants

CCI’s official primer usage chart specifically describes the #450 as a “Magnum primer for ball propellants.”

This is an important product characteristic for anyone researching CCI #450 primers.

However, a general product description should not be treated as a substitute for specific loading data. The correct primer and load combination should always be determined using current published data for the exact cartridge and components being used.

Is CCI #450 a Small Rifle Primer?

Yes.

The CCI #450 is a Small Rifle Magnum primer. CCI places it in its Small Rifle category and distinguishes it from the standard Small Rifle #400.

The word Magnum is part of its product classification.

Is CCI #450 the Same as CCI #400?

No.

Both are CCI small rifle primers, but they are different products.

CCI identifies:

• #400 as Small Rifle
• #450 as Small Rifle Magnum

CCI’s official primer chart gives different product descriptions for the two primers.

Because primer characteristics can affect cartridge performance, a substitution should not be assumed to be equivalent simply because both primers fit the same broad size category.

Is CCI #450 the Same as CCI #41?

No.

CCI lists #450 and No. 41/5.56mm as separate products.

The CCI primer chart identifies the No. 41 as a military small rifle primer with NATO sensitivity, while #450 is identified as a magnum primer for ball propellants.

This makes product identification important when researching primers for a particular application.

Is CCI #450 a Match Primer?

The CCI #450 is classified as a Small Rifle Magnum primer.

CCI separately identifies its BR4 as a Benchrest Small Rifle primer.

Therefore, the #450 should not be described as CCI’s benchrest or match-designated small rifle primer.

CCI #450 Packaging and Part Number

CCI’s current catalog lists the CCI #450 under the Small Rifle category as 450 MAG.

The catalog gives the boxed part number as:

CCI #450 — Boxed Part #17

Older and newer packaging can look different, so the product number and manufacturer identification are useful when comparing listings or checking inventory records.

How to Identify CCI #450 Primers

When checking a package or product listing, look for the following information:

1. CCI as the manufacturer.
2. 450 as the primer number.
3. Small Rifle Magnum as the product category.
4. 450 MAG. as the CCI catalog designation.
5. Part #17 when referring to the boxed catalog product.

These identifiers help prevent confusion with CCI #400, #41, BR4, and other primer products.

Handling and Storage

Primers are energetic components and should be handled carefully.

For storage and handling, follow the manufacturer’s current safety information and all applicable laws and regulations.

General safety principles include:

• Keep primers in their original packaging when practical.
• Keep them away from heat, flames, sparks, and other ignition sources.
• Store them in a cool, dry environment according to applicable manufacturer guidance.
• Avoid unnecessary impact or friction.
• Do not attempt to modify, dismantle, or alter primers.
• Keep primers away from children and unauthorized users.
• Follow applicable transportation and storage requirements.

CCI provides safety information and documentation for its primer products. Product packaging and current manufacturer instructions should take priority over general internet advice.

Important Loading Data Note

Primer selection is part of a complete cartridge-loading system.

Changing a primer can change ignition characteristics and can affect pressure and performance. For that reason, do not use this product description as loading data.

Always use current, published data for the exact cartridge and components being loaded. Do not assume that replacing one primer with another will produce identical results.

This is especially important when moving between standard and magnum primer classifications.
