(english) Gordons Reloading Tool GRT and how powder models are developed

[@AntiPattern328]

You are freaking amazing! The amount of research into all this must have been immensely difficult. I had some questions recently and got a response within a day explaining fully what I was doing wrong with my reloading data. Can't thank you and your team enough. You guys are awesome.

I'm just getting started with the software and I have much to learn. I've been hand loading for decades but this is a technological jump for me. I'm looking forward to the learning process I will happily share any data I can to help with the development of this amazing tool. Thanks for making such an incredible contribution to the reloading community and I will be making periodic donations to say thanks and help with your future developments.

Thank you so much to your team for taking on this project. I've just started looking into your tool and am eager to see it progress.

Hey so when doing the obt method in cassies video he talks about changing the initial pressure to match your measured velocity. I did a load with a 223 wylde chamber that was berger 75vld with shooters world precision rifle 23.5 grains and seated at 2.494. I had to drop my initial pressure from 3400 down to 2230 to get my measured velocity. Am I doing this right and is it safe?

[@mike-synthetica]

Thank you, this project looks very promising.

Hi I downloaded the software today and it looks great. Still checking everything out. One thing i noticed is there is no cartridge for a .260 Rem Ackley Improved. How do i go about getting it on the cartridge list?

[@TALLA300CforumZ]

I tried to join the Discord link, it says 'Invite Invalid' I've heard this so many times in my life. Sigh......

[@jakeannarino2602]

The Discord invite is not valid., or I have done something wrong.

[@GordonsReloading]

[@ryanjames170]

really looking forward to a alternate to Quickload, hope someone is able to provide data on the missing powders

[@GordonsReloading]

we working hard to make this happen, just participate by measuring your loads and share that with us

[@GunsNReloads]

Thank you so much for this software! I just made a video on my page talking about it!

[@YERAFirearms]

I like your accent.

[@GordonsReloading]

first video in english ever (spoken), its just not my thing talking in a different language as german, seems that it is not that horrible

[@YERAFirearms]

Looking for IMR 4066 and H4350 and H1000 powder data I can provide MV data accuracy reports

[@GordonsReloading]

would be helpful, please just download the template file (see video description). read the notes tab and from there we can start developing new powder models and/or checking existing ones. join our discord server and drop me your grtload files.
