Weight for weight the smaller diameter should have a higher SD and potential for penetration. I was just over simplifying with my statement. I will probably add a 6mm ARC for the same reason I picked up a 6.5G. The Grendel is a more cost effective 6.5mm alternative to my 6.5x55 and the ARC would be a more cost effective alternative to my .243. The ARC should be easier on the barrel as well. The .243 sure does get hot quick.
