I didn't find any data out there so I used Hodgedon's 168gr BTHP data with a different COAL. The COAL I used is 10 mils off the lands at 3.405". Looking at bullet dimensions this should create approximately the same amount of internal volume.
However, my hottest loads today were running 2740fps with 57.5gr Varget rather than the 2850-2900 fps I was predicting.
Is anyone loading this combination and how much powder have you found to be max?
