Wife has fallen in love with the 6.6 Creedmore after nailing bulls eye every time at 400 yards, she has a AR15, can I get a 6.5 Creedmore upper with a High Quality scope to place on the AR lower or is the 15 to small?
ThisAR15 is too small. You have to go AR10 lower.
What is difference between Grendel and Creedmore?
They are completely different cartridges that happen to use the same diameter bullet. The Grendel is shorter, which means it can be used in an AR-15 platform.
The Grendel is a brain fart from Bill Alexander. I remember talking to him about this chambering when I first acquired one of his 50Beowulf's. (about 2003)
Basically . . . the CM has quite a bit more potential other than so stated above. --- SAWMAN
