Interesting...based on the premise of 1,800+ fps, yes?
Depends why you have a Grendel in an AR receiver I suppose...
Not much difference between 400 and 500 yards for such a big difference in rifle weight and profile. I have always thought that if you are wanting a 24" barrel with all the length and weight that goes with it you may as well go an AR10 platform and use .260Rem for similar weight, same bullet and more case capacity. It is all about proportion; the receiver (which is a light-weight AR15 frame) the barrel length, and the scope. So, big scopes and long barrels belong on larger receivers for more dedicated supported shooting.
Yes, we love our Grendels but to put it in perspective the AR15 is a light-weight alloy receiver, designed as a short-medium range auto-loading military platform for 10-20" barrels. 400yards form a 16" barrel is plenty of range for most shots you will take in normal country. Anything further and your group size is getting larger than the kill zone on the target and you should be looking at stronger receivers capable of more precision to ensure early kills. Dare I say it... a bolt gun in a larger calibre with a longer barrel and a bigger scope, for long shots from a supported shooting position.
