Reloading software. What to use ?

So what is the currently best on line reloading software to use ?

My needs are maybe slightly different from most who are reloading nitro bottleneck cases.
Main differences are

Wildcats
Straight wall cases
Sometimes BP
Large capacity
Vintage obsolete cartridges

Pressure is a huge consideration in most of these applications.
Oldest cartridge rifle is 165 years. Most are around 125 plus years old.
So reliable pressure data prediction is important to decide on a load that can safely and repeatedly be used.

I have been told that the software doesn't really do BP well and I also see on line that people say it's not so reliable on straight wall cases.
I'm an experienced reloader and reload over 25 calibers for over 30 vintage ( and a couple of modern ) rifles.
I don't shoot target rifles and I'm not after bench rest accuracy. Neither the rifles or myself are up to BR !

To complicate things I am playing with a couple of wildcat creations of my own making at the moment. That's no real problem though because there are plenty of similar old cases to compare data from and draw conclusions on how to run them.

The other complication is most old cartridge printed data and forum data is from the USA and with the current ( maybe for ever ) powder shortages a lot of those powders we don't have access to.
Thankfully ADI is just across the ditch and they make a lot of those USA branded powders.

It would just be nice to cross check the data I have accumulated from on line with available powders and double check the pressures

Cheers

Gordon's reloading tool or quickload. Gordon's is free but won't be updated anymore. Quickload is not free but does get updates, which you have to pay for

The team are working on a new version of GRT. Expect it to be available in a few months.

This was on the GRT discord forum. It's being worked on as we speak. :thumbsup:

have GRT and quickload.

prefer GRT by a large margin.

The calculations I come up with usually end up within a few fps to actual measured velocities, (at least for the reloads I do) which I reckon is quite impressive.
