Match Grade Machine (www.matchgrademachine.com) currently has 2 24" Contender rifle barrels in 6.5x30-30 AI in their existing inventory.

It's essentially the 6.5 Bullberry IMP if you wanted to go that route with dies.

I have no ties to the company but wanted to share this info. I've had three of their barrels now, including a 26" in 6.5 Bullberry IMP, and the quality has been nothing short of terrific.
