You can get sub moa with most factory ammo and sub 1/2 moa with good quality match ammo or handloads. And that is in a 5 shot group. Most of these guns claiming sub .5moa are shooting 3 shot groups. I don't put too much count in 3 shot groups, I like to see nice tight 5 or more shots. Seems like it tells a little more about the rifle.

Also, you probably already know this but the bergara , even though it is in a regular stock, is actually a chassis rifle. It sits in a mini chassis. Pretty neat concept when you see an exploded view of it.
