I'm thinking the Fusion rounds are crap. I bought 6 boxes of 6.8spc of it on a closeout @ WallyWorld for $11.99 each and all of it grouped like crap out of 2 different guns. So DONT worry about it. The brass is good !
On your load of 44gr , there is a reason it says starting load ! Start there ! Then work up ! Nuff said ...!
