Thread: 300 Blaser Magnum

Has anyone got reload data for the 300BM? I'm thinking vit N570 will work well

I'm using 2217 and it's looking good so far still developing the load. No experience with N570. With 2217 started mid 70s. Feel free to pm. There's not a huge amount of info out there.

Here is some info I got.
