I have 3 Axis and 4 12FVs. With the exception of my .308 Axis (the only one in stainless, for what it's worth) all will easily shoot sub MOA. But the 12's will keep doing it after the skinny barreled Axis ones heat up. Both triggers can be made the same once you put the varmint spring in the Axis. I do prefer the larger bolt handle and open action in the 12's.

Honestly, they are both great guns and I think it comes down to what you want to do with it. Carry the Axis into the woods and use the 12 on the bench...
