If the 6.5 grendel is so good, logically wouldn't the 6.5 creedmoor in the Ruger SFAR be perfection then? That's what I'm strongly considering. Was going to buy one today but went home with a 224 Valkyrie that I just couldn't say no to. If it doesn't work on pigs though, the SFAR 6.5 CM will follow me home for testing.
