It all depends on the day and the shooter. Most all of the Hunter class rifles have been modified in some way, or complete custom barrels, which many actually listed as "custom". Some did not.

The Knights cleaned house this year along with an Omega. They had custom barrels. Greg was shooting that Omega with a Brux.

Jim was shooting the same rifle I shot, just my scope put me into Unlimited, being larger and weighing more.
