From what I am seeing the more popular cartridges are right on. I tried it last night with a 357 Max and it was giving some crazy predictions. When I get more time I am going to mess with it more.
Just downloaded and tried newest version, seems to be close in 308W and BO. Mo better than when I first tried. Don't like the color scheme, hard to read.
edit: seems like everything I tried of my loads were pretty close, used jacketed FP bullet data for cast and still close. LeverE powder keeps getting warning about inaccurate results but very close to my chrony results. Even unique 30/30 loads are close. Haven't tried any pistol loads yet. Appears to be a confidence/tested indicator for powders but can't tell if it is case related or not.

Same here, I downloaded and ran numbers against the book loads and its projecting pressure way over what the books are showing, I just started using it and there are a lot of things than appear to need to be manually entered so I can't judge yet but from what I see the numbers are a bit on the high side, I will play with it some more over the next week or so and see what I can figure out, be great if it works right....
Yea, doesn't indicate what is editable or not. I used the 'simple' panel - check for mag glass symbol for cal, bullet, powder and load and verify they are the correct ones (or use the tool bar at the top). Some pop-ups say 'use' or load', somewhat confusing. The OnTarget clone does a good job. And it's FREE.
I am not sure what to think of it yet, It appears to work on some things but questionable on others, may just have to do with the database size, does anyone know if it auto-updates, I have noticed that yet - I will probably use as a baseline generator for now, I haven't added any of my files to it yet but then again I haven't used it more than a dozen times so far. It does seem to work at least with the available database. Wonder if anyone has quickload database to share??

Grt will can use QLs bullet files. But not its powder. There is a special note on the website about that. QL uses older math and models while GRT use more modern math and models. But it takes a lot of sample data to make more accurate profile. Their website has information on how to submit profiles. They are in need of western profiles last I checked. Been meaning to join their Discord to see what information is in it.

For whatever it's worth NOE has a full QL catalog pdf on the store site for all of their bullets . Somewhere in my wandering I found 8-10 page list of weight/dia/BC for at least 6 mould makers . Lyman , RCBS , and Lee present . Seaco and Hoch also .......maybe that was all of them .
IMHO it needs powder input from users. No CFE blk & others. The bar next to powders is the 'reliability' of powder data. Those with labradar or blade chronys could add a lot of gun, case vol, load data and fps that will increase the 'reliability' factor. I did find some Lee cast in the data base.
The github site has no project info so IMHO it probably will go the 'pay' route when data is better. Basically proprietary software.

Well I have been playing with the software for a couple weeks now and I think I got the hang of it, I agree they need to expand the powder list, I thought about emailing the powder company's myself and entering the data. I created about a dozen bullets on the user database both cast and some of the other brands I had on hand that didn't appear in the database. However I do agree with popper I am reluctant to send them a bunch of data and end up having to pay for something I contributed to. On the surface it seems fairly accurate, I would not be afraid to use it as a base line. especially for downloading cast rounds, it gives me a pressure/time curve I can use to make sure the round will still cycle the action and I can get an idea of what a new load should do with powders I don't have. They definitely need more data points for a lot of the powders they do list so I know that will reduce the reliability of the calculations, too bad one of those guys that are working on the program doesn't shadow this board would love to chat with them. But overall I do like what I see and it has a lot of possibility's I plan to keep using it and building a database on it, maybe contact them and see if they willing to work out a deal with people that contribute. I have a fair amount of real world data I could put together and I am sure others here on the board could do the same.
I put together my bullet list last night and have over 1200 individual slug data entry's in just 223/9mm/45/308 alone not including my real world cast data for about 30 more molds including alloy variations, I have a bunch that they don't along with 600 or 700 test shot data records. also found a bug, when using the imperial units as measurement. if you set the case volume to cubic inches and adjust the preset oal (cartridge length) it blows away the case volume calculation at lease in version 1812 and screws up the simulation. Rcmaveric or (anyone else) check yours out and next time you on their board let them know
Ok, I just noticed with my cast results things were not quite jiving up and figured out why, when you add a new bullet you have to adjust your initial pressure to match the type of bullet, ie. copper jacket, soft lead, hard lead, brass/copper with/without driving bands, buck/slug they all have a dif starting pressure and will change the results quite a bit, once I put that data in correctly the numbers were much closer to what MFG data books showed as correct loads. Not a bad idea to also check the pre-programmed bullets as this is not always correct I have found.
