Firearm Cartridge Library

It’s been a long and interesting end to the 2014 year, but it has been a productive one and I am happy to move into a fresh new year with new possibilities. With it being so busy however, I have not been able to write much recently. But rest assured, I have been hard at work at something I am very proud of..

With the 2014 year coming to a close, I am happy to announce that the Firearm Cartridge Library has officially released online in a BETA test version 1.0.x. The Firearm Cartridge Library is a large and ever-growing database of Firearm Cartridges. In the initial release, 235 Firearm Cartridges were released online in the library under the Pistol Cartridge Category. These include cartridge data on everything from the extremely tiny 2.34mm Rimfire up to the .50 Caliber class cartridges like the .500 S&W Magnum and the .50 Action Express.

Some of the Data you will see in the Firearm Cartridge Library:

In the coming days, weeks, and months, you will see a steady stream of updates to the library with new data being entered nearly around the clock. Into the first week of 2015, you can expect to see the Rifle section of the Firearm Cartridge Library open, with hundreds of Rifle Cartridges to view. The Shotgun section will open soon after this.

A few things to note: Not all data is complete yet, and not all images are finished for each cartridge. This takes some time, but I can assure you I am burning the candle at both ends to get this done. Regarding pressure specifications for different cartridges, I have generally stuck to the most reliable sources when researching Case Pressures for all Cartridges in the database. When possible, the first information researched is always the official specifications as put for by both SAAMI and the CIP. When using information found on this website or any other resources, always be sure to consult a professionally published reloading manual or other official resource to compare data. When possible, always check multiple sources, regardless of how much you trust where your cartridge data is coming from. One last note, please make sure to read the site Terms & Conditions as well as the disclaimers within the Firearm Cartridge Library before using the data found in our database. We are not liable for how or why you use the information found on this website.

Official Firearm Cartridge Library Release Schedule

The official release of the Firearm Cartridge Library is scheduled for the first week of February, 2015. At this time, I believe mostly 100% of the Cartridges should be up in the Library with data and images, as well as the completed versions of the features listed above. Past this point, the future holds a lot for the Firearm Cartridge Library, and you can expect to see some really cool updates with awesome new features that are already in the works. I would list them out for you here, but I think I will wait and keep some things as a surprise!

I think that about sums it up for now. Thanks for reading, and as always take care and be safe. I’ll check back in the New Year!


  1. Is very difficult to find information on bullets. It seems as if the information is provided for the weapon itself but when it comes to the effectiveness of bullets this the most detailed information I’ve ever seen.

    • I’ve kinda come across the same thing. The internet is full of a lot of information, but when it comes to factory load performance, it seems a but scarce at times even from the manufacturers themselves. I’ll keep it coming, I have a few more tests on the back burner waiting to be posted.

  2. When everything is finished and all put together I think this will be an awesome reference for everyone who owns a firearm or is interested in firearms. Having information about all kinds of cartridges in one spot is brilliant.

    • Thanks :) There is a lot of work to be done, it is an ongoing project of mine. It is taking a bit long than I expected with all the research and information, but in the end I hope it is at least helpful for others.

  3. It’s amazing how ammunition has involved over the years it seems as if new rounds are going to be coming onto the market pretty soon we might start to see some things that are incredibly unique. Unfortunately the actual interesting rounds are reserved for the military.

    • There are definitely some cool ones. Unfortunately, they are mostly reserved for Military and LEO use and illegal in many areas. Makes sense why, but it would still be fun to be able to test some of them out :)

  4. Is this library still being worked on? I have not seen anything else as far as posts. I would like to see more updates on the library.

    • It is being actively developed, although I haven’t kept an online log of the version changes. The Rifle Cartridge library has slowly been added, with a few hundred entries. I am hard at work generating content such as reference images, resources, and other articles to supplement some of this information. Thanks for asking! Hopefully I can migrate to an only history of version changes soon.

      • Okay that is cool to know about the rifles been added slowly. It has been slow on this blog lately. What else is being added to the cartridge library?

        • Quite a bit actually, although I can’t touch on a lot of the details at the moment. Diagrams, pictures, and notes are being added bit by bit as time allows, but as you can imagine its a lot of research and work so the process isn’t as quick as I’d like!

  5. That is cool news for this blog. Maybe now some more people would find the info they need about cartridges. I find that knowing more about the different cartridges would be useful. I’ll check this thing out so I would be able to learn a lot more.

    • I agree this is a great reference for everyone who has a firearm or is even interested in firearms and their cartridges. I will definitely keep checking this out as updates are added.
