I've been trying this out. Has anyone else been using it? How close has it been with estimating loads (especially pressure) in handgun cartridges?

I'm never too bashful to ask. What is it? I've never heard of a Gordon's Reloading Tool.

Gordon's reloading tool, GRT, is similar to quickload and is a free download. It does have some different powders in it.
I tried it next to quickload and got different results. He has passed away, so no more updates.

I’ve found that if you have your case capacities, cartridge length, bullet length etc correct (ie measure for your components) that it has been pretty darn close to chronographed velocities from my equipment. Replicating published load data in the program seems to get close to published pressures. I have fun with it, but as was mention Gordon passed away.

I know he passed. His wife is trying to find someone qualified to maintain it, but the existing data should be good. I like it so far.

So, it's a computer program or an "app" for the phone? No wonder I didn't know what it was.

It's a computer simulation that seems closer to published pressure results with handgun cartridges than Quick Loads so far. It's also pretty good at predicting how much unburned powder in a load.
I've actually backed off a couple of my loads after running it's pressure simulation versus Quick Loads. I knew they were higher pressure, but they were higher than I thought according to Gordon's. Quick Loads has trouble estimating handgun cartridges pressures.

I keep seeing references to it so I bookmarked and registered. Prolly too complicated for my feeble old-guy brain to grasp, but I'll give it a whirl.

I want to give a shout out to GRT. I downloaded it a few days ago after not wanted to pay for QuickLoad. The creator has passed away, but it has been picked up by a set of programers and carries on. I have been very pleased so far. Pretty simple to get going and has hit several of my handgun loads right where I chrono'ed them. I have measured and entered my projectiles and case volumes. It certainly does not replace loading manuals, but not everything is listed there and this has helped me a lot. If this sort of thing interests you the price of entree is right: Free. The claim is that a new improved open version with be coming out within a year. This one is pretty good. URL: grtools.de/doku.php?id=start |

Replicating published load data in the program seems to get close to published pressures. I have fun with it, but as was mention Gordon passed away. My experience mirrors yours. I have also found that adding a barrel gap for revolvers help to predict velocity. I have no idea of actual pressures but predicted velocity is typically <20 fps for measured velocity by either magneto speed or lab radar. -Freeze |

I am downloading it now to try it out. There is no such thing as too many tools in your toolbox!
