Hi All,
Need some help, looking for load data min/max for WIN 748 using 39 Sierra BLKs. Been searching all over and cannot seem to find specifics, many refer to load data for 40gr VMAX, but quite difference in bullet. Appreciate if anyone is using same to steer me in the right direction. Cheers

You will be safe using the 40 data with the 39 SBK provided you follow safe load development practices. Doesn't matter what anyone else has done safely with a combo because every rifle is different. Start at the lower end and work up to what your rifle likes watching for pressure as you seek the performance you are after.
