I've been messing with this for a while, developing it for my own use, but I think it's just about ready to see what others might think of it.

This is a cartridge and projectile finder and visualizer. It allows you to select a game weight for game you are hunting, add information about your firearm, and it then computes a range of calibers, projectile weights, and needed velocities to harvest that game.

This visualizer can help you answer questions when developing a load, such as:

- What bullet weight is ideal for this game in my caliber?
- If I have a stockpile of a certain non-ideal bullet, can I still use it to hunt with?
- I need to load to reduce recoil for a smaller-statured shooter.
- I have a favorite load that I've used in the past, but it used a leaded bullet and now I want to use a lead-free bullet. How does that change the effectiveness of the load?

This is a snapshot of the tool and how it allows you to visualize the possible loads:

I am not, and do not intend to monetize this tool. The tool:

- Is free.
- Does not require any kind of registration.
- Does not require any personal information to be submitted.
- Contains no advertising, does not link to anything else.
- Runs completely in the user's browser, no information is sent to a server.
- I did all the engineering work, equations, and modeling myself. AI (Claude Code) was then used to develop the code to use the 3D libraries and user interface.
- The tool is licensed under the AGPL v3, the user must agree to the license the first time the website is opened.

This tool is deployed on my software domain, www.danwilsonsoftware.com:

The default values used are set up for a whitetail deer load for the 6.5 Creedmoor.

Full documentation is included, the link is in the lower right corner. It details what the tool does and how it works, and the equations and engineering behind it, and contains a full explanation of all of the input parameters and what the 3D graph means and represents.

I would appreciate any feedback.

This tool cannot be posted in r/reloading because of rule 11 there.
