At normal hunting/stalking distances that might be true enough but OP did say he's looking to get out to 800m with this.
Won't make a difference for varmints and small game but the energy it's carrying will have really dropped off by 800m.
100m 2,300 ft lbs energy
400m 1,500 ft lbs energy
800m 750 ft lbs energy
At the far end of what we're talking about IMO bullet construction has become important.
The heavy ballistic tip have good enough BC and are designed for hunting.
A-Max are offered as match bullets, people report good results hunting with them but at more typically distances of 100m - 300m. I really couldn't comment for using them out to 800m.
Game King are proven hunting bullets, their 165gr and 180gr boat tails boast good figures.
