GRT - Gordon's Reloading Tool

#1

I came across a freeware reloading program - Gordon's Reloading Tool. It looks similar to QuickLoad. I thought I'd share the link and check if anyone has used it.

Very interesting and this is the first I've heard of it. I don't have Quik Load on my computer, but I've had others run my data and furnish me a copy. Really excellent tool, but not perfect. Things like time to pressure max, heat of explosion, load density, predicted pressure and velocity are just a few of the data points. If the Gordon's Reloading Tool is as good . . .

It till needs more refinement. If the predicted MV is far away from real MV by more than 5% it is still far off. Right now, it is 10-15% off.
However, once the simulation program is refined, it would surpass QL.

For some reason, internal ballistics programs don't seem to be as popular in the US as Germany. I use QuickLOAD and find it a very useful tool. Gordon's Reloading Tool (GRT) is in the early stages of development but I like the interface better than QL. It has a lot of promise. What they need now is more data (brass, bullet geometries and muzzle velocities. Pressure trace data if you have it) especially on US powders to refine/develop their models.

Go check out their website.

I want the GRT to surpass the QL
I want it to be more accurate in predicting MV and Barrel time.
I want to be Beta Tester
I want to be data provider if I can (MV and load info)

I just downloaded the latest beta. It is 10X better than the first beta. Graphics as before are very cool. More data are in and more features and it seems accurate. I run my load for 243 but with 4064 instead of the new version IMR 4166 and it very very close to the MV I was seeing. That was with no teaks at all.

This app would have a lot of use by me.

Be sure to check out the OBT tool added in this latest beta. Nice touch.
