With the recent release of this bullet combined with COVID-19 issues, there just doesn't seem to be a whole lot of info available on their performance as yet. I keep my ear to the ground about such things and the preliminary reports I've heard have been very positive. However, I have heard no specific information regarding velocity, seating depth, etc. Solely based on my loads with 200.20Xs and 215s over Varget, my guess is the 208s ought to tune in somewhere close to 2600 fps from a 30" barrel. Obviously there are other faster/slower nodes, but 2600 fps with a powder such as Varget would be a good combination of case fill ratio, pressure, gun handling, performance, and brass life.
