I will soon be working up loads for my 338 Lapua and am able to get Viht N565 in my area. They say this powder was developed specifically for the Lapua, but the load data in the Viht manual looks very light. This seems to be the case with most of the Viht data though, so I’m wondering if anyone here is using it and what kind of velocity/accuracy you’re getting. I’ll be loading 265 gr Nosler Accubonds and 270 gr ELD-X but any data you have would be helpful.
