there is a lt to be said for a shorter barreled Grendel or anything else to a point. If you doubt the effectiveness of a 14.5 barrel look at he 16 inch barred data on Hornady's website. From what I consider a very good source that data is actually from a 14.5 inch barrel with a flash hider making it 16 inch over all.
Almost all barrels are a compromise for length, just about every cartridge out there can benefit some from a longer barrel up to a point where expansion ratio and bullet friction and mass in the barrel overcome the push provided by the burned powder. A 22 Short, Long and Long rifle are good examples of the latter. Standard velocity 22LR is actually slowing down in a 24 inch tube.
Guns, cartridge selection and loads for them are all a trade off.
