Hint: If you open this website in a second web browser tab, you can follow the video in one tab and register in the other.

Hint: You should be able to find it by searching your email client unless you deleted the original “noreply@grtools.de” or “notifications@grtools.de” email.

If you know your Username, but not your Password, you can request a new Password at the bottom of the registration page.
As soon as you see the green stripe announcing that a new Password has been sent, close your browser, and look for the new notification email.
When you find the new notification email (look in your Junk/Spam folder), click on the URL at the bottom.
That will relaunch the GRT website in your browser and a new notification email will be sent with a new Password.

If all else fails, simply create a new registration using a new Username. Multiple Usernames per single email addresses are allowed.

I just wanted to reach out and let you know that my husband Gordon passed away on January 19th 2022.

Until further notice, this site stays online. Please note that Patreon contributions have been paused.

Initially, no additional submissions should be made to the GRTLab, or Translations, as no one has access to service the data.
Therefore, it will be impossible to update Powder Models, Calibers, and Bullet to the GRT database as an official release until the possibilities of continuing Gordon's fine work are explored.


Take care!

February 2, 2022 - There are newer updated versions now available to everyone. The Windows version has an End Date for the year 2048.

February 4,2022 - A new Linux version is available today with the end date set to the year 2048 similar to the Windows version.
This version is listed as V2040. It Shows V2040 on the File menu / About screen.
I was able to revive a VMWare Player, Linux implementation, locally after not having used it for a couple of years.
I was able to run the V2040 Linux version on it, and manually advance the system date to Jan. 18, 2046 before I received any out of date message on screen,
so it appears the single byte patch is working. I was able to perform a Save As to a .grtload file, and then open the original file.
Therefore, I believe the patched V2040 version for Linux is working as before.

March 15, 2022 - With the recent influx of new GRT users, a problem has appeared. It seems some email services are trashing the GRT Login Account Verification emails.
The prospective GRT User does not even get the verification email into their Junk/Spam folder as their email service trashes them before forwarding these emails.
GRT Verification emails are addressed as From: noreply@grtools.de. Prospective GRT Users need to white list emails from “noreply@grtools.de”.
Affected emails services such as Earthlink, Comcast, Hotmail and ATC Broadband have been noted as problems.
We suggest that if problems of this type are experienced, the Prospective GRT User should get a free Gmail account for registration use.

May 9, 2022 - An additional account start up problem appears to be taking place. Some Users have reported that they do not receive a verification email.
The problem may be that the User is using part of his email address as a Username (i.e. “Gismo” when the User email address is “Gismo@domain.com”)
When this happens, an account is generated, but the User does not receive the confirmation email with password.
Please avoid using any part of your email address as a Username.

June 8, 2022 - Reference to March 15, 2022 message above. The outgoing verification email address “noreply@grtools.de” has been changed to “notifications@grtools.de” in an attempt to bypass those email servers that may place “noreply” type addressing into Junk or Spam inbound folders. Never the less, prospective GRT Users should still check their Spam or Junk folder if the verification email with password is not received within just a few minutes. It has also been observed that sometimes a new Registrant has to use the “Set new password” login option in order to receive a password. This triggers a different routine to the password process. In this case the User should close his browser completely and just respond to the “Reset password email that should arrive shortly. Responding this way will open your default browser, and the next email from Grtools.de should contain a password.

July 2, 2022 - A small problem has been discovered in the Projectile Export function of the Linux version of GRT. This bug makes it impossible to share exported Projectiles with other Users as the Import function will fail. We have constructed a fix that will hopefully be available on the website download page in the near future. In the meantime GRT Linux Users can email “charlie@grtools.de” or contact “Charlie” on the GRT Discord Server and he will provide a link to his Google Drive so the fix can be downloaded. This fix will be in the form of a archive file with extension .tar.gz. Once the archive is extracted the User simply replaces the GRT executable file in his current working folder with the new file. All other functions remain the same. It has been noted that when exporting Projectiles with the GRT Linux version, the export filename is missing the .projectile extension. Ensure that you add that extension name when doing Projectile exports.
