My RA in 6.5 CM shot under an inch with a virgin barrel using Lapua 108 grain Scenars.
No break in required.
It's hard to argue with sub-MOA right out of the box.
Glad I picked up 500 of those 108gr Scenars recently too when Midway was running a clearance on them. I'm hearing good things about the 120 Scenar-L as well. My experience is limited to the 123gr Scenars, but they are quite impressive for the money when you can get a deal on thrm.
