Norma MPR powder load data

[dgr416]

Where do you get loading data for this powder?I deloaded 1200 Norma 416 weatherby loads with this powder and have many pounds.I think it is close to R22 .I need loads for 338-378 weatherby and 264 win mag and 338 win mag if it works.I think it is too slow bruning for 416 rem mag.

go with RL22 data, but start 10% down and work back up .
