GRT Update
- Thread starter Neddle
- Start date
I do believe Gordon has passed away.
Website announced he had sadly passed and said updates would stop. Wonder what will happen with it.
If you get the current version it has been adjusted so that it will not expire until 2048 I think. That'll see me out. Prior to that Gordon expired it frequently, to ensure you to updated to the latest. Not a bad idea, it was only ever in "Beta". For about four years.
Still quite usable, with quirks, the aficionados seem quite zealous about some of the advanced features.
Is it/was it a better mousetrap ? You be the judge of that.
The prospects of the important parts being kept reasonably current, or feedback from "the community" primarily to refine the powder models, being absorbed, or advancements made, seem to me, ATM, remote. It won't stop working, but I suspect will remain frozen in time.
I get the impression that Gordon kept the codebase to himself, and that is probably inaccessible,, maybe a lot of the detail of it was in his head, or in his own documentation, or at least beyond the comprehension of a mundane coder without a deep knowledge of the detail.
But I could be completely wrong about that, and hope for a renaissance. Meanwhile I'm not spending too much time getting to know it

If you have got the (final ?) version like mine, it will be a zip file containing the Windows version in a zip file, the Linux version in a tar.gzip, and the manual in a .pdf
All dated 17 April 2022.
If you are using Windows, the built in file manager can open the zip file, inside which you will find the Windows version zip file called gordonsreloadingtool-2021.2030-nightly.zip
AFAIK this is the most recent version, .2030
Extract that and inside you will find yet another file called gordonsreloadingtool-2021.2030-nightly
No file extension, but it is a .zip file.
Extract that lot to your disc (don't try to run it from inside the zip archives) and inside you will discover the installation files and sub directories.
The installer is gordonsreloadingtool.exe
The config file would be gordonsreloadingtool.cfg I was not aware of the need to remove it, but maybe I'll take a look inside and try to figure out why it might not be quite right. I run Win10 BTW.
Sort of like unpeeling an onion, rather than simply downloading a program in the usual way where it's all done for you, but not too tricky, even if you've never done this sort of thing before..
I'm using it on a 2022 MacBook Pro in Parallels running W11 after my previous Mac died. I had to start over again for the calibres I use due to various incompatibilities but I didn't have any problems getting it up and running. I quite like it but cross reference rigorously with other sources, Vihtavuori, Sierra, Hornady, Lee etc. and always work up loads safely.
Concur with @Sharpie on what he's said.

OK I've taken a look at the .cfg file and this may be the problem.
[GordonsReloadingTool][2021.2030-NIGHTLY][CFG]
AutoCheckUpdate = true
DontAskAutoCheckUpdate = false
LastUpdateCheck = 3720417997.6859999
LicenseDontShowAgain = false
If you allow it to do that, it will be constantly trying to check for another update. Even if the server is still operating. Which won't be happening any time soon. When it detected a newer version available it would want you to update and re-confirm your license.
The numbers appear to have been tweaked, but I am not familiar with the format, just guessing, that might expire it sometime in 2041. Unless some other date has been hard-coded in elsewhere.
Me, being me, I'd probably edit out that that part and leave the rest of the .cfg file alone rather than remove it altogether, but YMMV
From the announcement of Gordon's death, Jan.19 2022:
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.

I just wanted to interject about those of us who use the advanced features being somehow “zealots”. That is a ridiculous statement! Gordon designed the suite with fine tuning loads as one of the key features which few other programs offer. It was in beta whilst sufficient data was gathered to tweak some of model sub routines and values to better reflect measured data and somewhat helpfully, he also included a database for users to contribute to or to build their own libraries, the outputs of which increase the model confidence levels as more data is added. This feature remains and if it weren’t for the “zealots” there would not be as much certainty for some of the more advanced features.
It is probably true to suggest that some of the detractors simply find the detail a little too complex, which may put them off but it is all pretty established ballistics. If there is no appetite for using and benefitting from the advanced features then There is little point in using it over a more generic tool such as PMax but as with all these tools you still have to work up and verify the results.
The key things to remember are that measured MVs relate directly to pressure with any given powder and there is no such thing as “free velocity gains” so if your load tests way over what powder makers suggest as the highest velocities, or indeed any modelled MVs then that tells you that you are probably over pressure and to reduce loads. Those who pour scorn on this are asking for trouble to be brought on themselves.

It was designed to time out after a number of months, to make sure you kept up to date on versions. Mine timed out last week, I downloaded the package from the website and reinstalled it in a new directory, then copied my loads over, and it all works fine. The version I downloaded won't time out for quite a few years, that's one change Charlie made when Gordon passed away.
To install, I downloaded it, then right-clicked and selected extract all. This created a GRT folder in my downloads directory, which I then copied over to another location on my PC.

Yes, I did the same. Very useful resource.

On the GRT I downloaded a few months ago there is no Vhit150, only 140-160.
Thats odd mine has n150.
