dont have one but groupes are relitive to the shooter, scope, trigger, bore .chamber, loads , action, bullets , barrel etc. as far as killing just like any other 7mm with the same bullet at the same velocity. i know i am being a ***. but there is nothing new about the 28 nosler. just go with a 7 stw, 7 rum or 7 swm with BERGER BULLETS. trust me the nosler coolaid dont taste that great.
