Remember with anything posted on the internet not coming from a manufacture's site should be checked. It is just too easy for people to make mistakes.

You might also want to contact Rainier to see if they have any information to help you.

If you are determined to try this powder without confirmed data then try starting at 4.0 grains of WST and you probably will find 4.4 is about right. I would not try going beyond 4.6 since the groups will be spreading out. This is a soft shooting load but you can't push it too hard since it is a very fast powder. You will find it burns pretty clean.
