I built a 12” 6.5 Grendel because I am only reloading for two centerfire rifle cartridges, 5.56/223 and 6.5 Grendel. I chose the 6.5 Grendel over the 5.56/233 for greater performance and less noise/blast from a short barrel. I mainly just wanted to play with the AR-15 pistol to see if I liked it. I don’t see myself getting rid of the AR pistol as it is quite capable at 300 meters or less in a compact light package.
The 6.5 Grendel starts out with more punch than a 300 Blackout or 5.56/223 (with the same length barrels) so at greater distance it’ll still have more punch. I can see more velocity from longer 6.5 Grendel barrels but if the range is short the extra velocity might not matter in terminal performance.
