It is a Savage Duel Port Target action in a Stockade Prairie Dog Special/Tactical stock. It has a 26" Brux barrel chambered for a no turn neck 6mm Norma BR. caliber.
A lot of people don't know what a 6mm Norma BR. looks like so here is a comparison to a .243 which is on the left. The bullet I used is a .105 gr. Berger Hunting Match VLD (very low drag). The barrel is a 1 turn in 8" twist.
