Cal74, read this thread on the Accurate Reloading forum. These groups were shot on a good rest in a tunnel with a $4000. rifle. As you will see most groups are around .800-1.00" Also top ammo was used. I will post another link of the testing they did with a Blieker rifle]$8,000]and with the top ammo in the World.

They changed ammo and the groups got smaller, about .562 average. Remember this is in a tunnel with the Worlds best ammo.
The next thread is of photos of the Blieker's targets. The group sizes are not measured correctly, but you can see what a $8000 rifle can do in a tunnel.
