Sorry that I cannot give you any information on the 6.5x47 Lapua, however, I can on the 6.5x284 Norma. I just acquired the firearm (Cooper Model 52) this year and had it to the range only once to develope loads. OMG, is this thing ever accurate!!! At 100 meters I have 7 targets that are sub-moa and5 targets are almost quarter-moa and one less than quarter moa. This thing loves any powder, however VV165, H-4350 are it favorite so far. Fired 139 grain Lapua and 140 grain Nosler CC. Now that the cases have been fired (Blown-out to tight chamber forming, and neck sized at 50%), theoretically accuracy should improve. This is the cartridge that has taken over the long distance target shooting (600 and 1,000 yards) because of the extremely high BC and low ES. Check-out the website www.accurateshooter............you will learn something there I'm sure.........I did.Good luck!!!
