Thread: found some "equivalent powder "commentary ( les you didn,t know )

I asked Chat gpt to offer commentarry about the equivalency of Hodgden and ADI. Now i already new about 2208 ,2209 , 2217 so it seems likely the rest listed are useful to know as well .

""Australian Defence Industries (ADI) powders are known for their high quality and are widely used by reloaders worldwide. Many ADI powders are rebranded and sold under different names, particularly in the United States through Hodgdon. Here's a list of some popular ADI powders and their equivalent or closely matching powders from other brands, mainly focusing on Hodgdon since it's one of the major brands that rebrand ADI powders for the U.S. market.

### ADI to Hodgdon/Other Brand Equivalents

1. **ADI AS30N** - Equivalent to Hodgdon Clays. This is a fast-burning powder suitable for shotgun and light handgun loads.
2. **ADI AP50N** - Equivalent to Hodgdon International. A versatile powder that works well in a wide range of handgun calibers.
3. **ADI AP70N** - Equivalent to Hodgdon Universal. Good for shotgun and handgun loads, offering versatility across a broad spectrum of calibers.
4. **ADI AP100** - No direct Hodgdon equivalent. A slower burning pistol powder for high-velocity, large caliber handgun loads.
5. **ADI AR2205** - Equivalent to Hodgdon H4227. This is a fast-burning rifle powder, ideal for small capacity cartridges.
6. **ADI AR2207** - Equivalent to Hodgdon H4198. Suited for light to medium bullets in a variety of cartridges.
7. **ADI AR2206H** - Equivalent to Hodgdon H4895. A versatile powder that can be used in a wide range of medium to large calibers.
8. **ADI AR2208** - Equivalent to Hodgdon Varget. Known for its versatility across many different rifle calibers, especially popular in .308 Winchester.
9. **ADI AR2209** - Equivalent to Hodgdon H4350. Suitable for a wide range of calibers and bullet weights, offering excellent temperature stability.
10. **ADI AR2213SC (Short Cut)** - Similar to Hodgdon H4831SC. A high-energy rifle powder for large calibers and magnum cartridges.
11. **ADI AR2217** - Equivalent to Hodgdon H1000. Preferred for its excellent performance in large magnum rifle cartridges.
12. **ADI AR2225** - Equivalent to Hodgdon Retumbo. Ideal for very large, overbore magnum cartridges, providing high velocities for heavy bullets.
13. **ADI AR2218** - No direct Hodgdon equivalent. Similar in application to AR2225, for very large capacity cases.

### Important Notes

- **Substitution**: When substituting powders, even between equivalents, it's essential to start with the manufacturer's recommended loads and adjust carefully. Powder formulations can change over time, and lot-to-lot variations can affect burn rates.

- **Current Data**: Always refer to the most current reloading data from both the powder manufacturer and bullet manufacturers. This ensures safety and optimal performance.

- **Availability**: Powder availability can vary significantly by region and over time. It's a good idea to have alternatives in mind in case your preferred powder is not available.

This list highlights the versatility and breadth of the ADI powder lineup and its equivalents in the Hodgdon range, among others. Given the dynamic nature of powder production and branding, it's always wise to verify current equivalents and load data directly from the manufacturers' official resources.""



I have found simaler commentary for Vihtaruori as well if anyone has the N stuff and are ignorant about possiblities . let now if you want that stuff put up .

Don't use ChatGPT without verifying anything. It excels at being wrong very quickly. It is a language model with very little intelligence.

Was going to say - this has potential. I've seen some spectacular clusterflucks come out of chatgpt!

Greetings All,
Another vote for using only pressure tested published load data preferably from the powder manufacturer (in this case ADI) or the wholesaler (in this case Hodgdon). Even then there can still be some gremlins. Special note needs to be taken of the actual projectile that the data is for as this can alter both velocity and pressure. Powders can vary in speed from lot to lot sometimes by design so working up a load needs to start low (but not below recommended start loads) using a chronograph to verify the data being used. My own paired trial has shown that AR2209/ H4350 has been sped up around 20 years ago but some data for the old powder is still published.
Never use any other data from the internet without first cross referencing with pressure tested data. This includes data I might post.
I note that one ADI powder has been missed. IMR 8208 XBR is BM8208 but with a twist. There seems to have been a slowing of this powder since its introduction. So far I have not done any trials on this but have detected that the earlier lots were close to AR2206 or a little faster in speed but my current lot seems to be close to the slower AR2206H. This seems to have been with both NZ and US data.
Handloading is one of those things that seems so simple to start with but the more we learn the more profound our ignorance seems to become.
Regards Grandpamac.

I agree with your statement on 8208 getting slower and this also highlights the need to test when starting new lot numbers for handloaders. The latest batches of 2208 also seem slower as well.
With 8208 getting to be similar in performance to 2206H it main advantage now is its smaller kernel size allows for better fill and metering.
The performance difference I see within the same case and projectile is now about .3 of a grain

The inaccuracies of ChatGPT have already been mentioned, but for those not familiar; it provides its answers from all data sources on the net, which means the correct sources and the incorrect ones together. It does not use reasoning and investigative research to rule out unreliable or incorrect sources of information. So it would be unwise to use it when doing your own research unless data accuracy is not of high priority.
