Are they the same or is data basically interchangeable? Seems like when I look them up on Quickload, they always have almost the exact same outputs. Anyone know?
Sorry, I'm not familiar with the elcho17. To be safe, I would not assume it's interchangeable with RL17. Just use the data provided by the manufacturer and press on with your own load development, no shortcuts, work up with a safe progression.
Apparently, RL17, Elcho 17 and RS62 are all the same thing made by Nitrochemie of Switzerland. A member of the Rheinmetall Group. No North American distributors.
RL17 is supposedly the original 7.5X55mm GP31 Swiss military cartridge powder.
Thanks for that. I was looking around but couldnt find a finite answer. Obviously I will work up the load, but in a lot of .308 simulations I am running, Elcho-17 is always in the top 3. Good to know.
You can see the properties are identical, so obvious QuickLOAD author Hartmut Broemel, who is an industry insider, was aware they were the same powder.
