The Best Online Reloading Resources: How xxlreloading.com Compares

Load Recipe: Brass, Powder Charge, Bullet, etc ...

Types of Load Data Resources

There are three primary types of online resources for reloading data:

1. Independent websites that provide load data for multiple powder and bullet brands (e.g., xxlreloading.com, LoadData).

2. Powder manufacturers that typically only provide load data for their own powders (e.g., Hodgdon, Vihtavuori).

3. Bullet manufacturers that provide load data exclusively for their own bullets (e.g., Hornady, Nosler).

Pros & Cons of Different Sources

Clarity on Input Parameters

A critical aspect of any load data source is transparency in input parameters, particularly cartridge overall length (C.O.L.) and case capacity. Variations in case capacity (even between different brass lots of the same brand) can significantly affect pressure levels for a given charge. Unfortunately, most resources only list the brass brand without specifying case capacity, which can be problematic for reloaders using different brass.

Additionally, some sources omit barrel length when listing muzzle velocity, making the data less useful. Always ensure you're comparing "apples to apples" when evaluating load data across different sources.

Range of Components Covered

Bullet and powder manufacturers typically only provide data for their own products. Given the frequent shortages and unreliable availability of reloading components, most reloaders use a mix of brands. This forces them to consult multiple sources—unless they rely on a comprehensive platform like xxlreloading.com or LoadData. Switching between different manuals or apps increases the risk of user error due to inconsistent formats.

Additional Features

The most valuable extra features a load data resource can offer include:

• Personalized load calculation (adjusting for case length, C.O.L., case capacity, pressure limits, fill rate, and barrel length).

• Digital load diary for saving and revisiting successful recipes.
  

xxlreloading.com is the only platform that allows users to tailor load data to their specific needs. It also offers a community-driven load diary, where users can share and compare recipes—a feature unmatched by other resources.

Summary & Evaluation

We believe xxlreloading.com is the most valuable online reloading resource for several reasons:

1. Largest database—appr 5 million loads (competitors have ~313K or fewer).

2. Broadest coverage—includes all major powder brands and most bullet brands in one place.

3. Personalized load calculator—unique functionality for adjusting load data to individual needs.

4. Digital load diary—store, access, and share recipes across devices.
   

For reloaders seeking comprehensive, adaptable, and community-supported load data, xxlreloading.com stands out as the top choice.
