I have 3 Alex Pro MLR's. I think they retail for $3,500 but you can get them on GunStroker for $2,200 - $2,500.
Mine are chambered in 26/30/33 Nosler, but they also make them in 300 Win Mag and 7mm Rem Mag.
Though all of those cartridges are 30'06 length (3.340"), the action, bolt throw, and magazine can accommodate 375 H&H length rounds (3.600"). The mag can actually handle a COAL of 3.800".
So if you're one of those Creedmoor type guys that likes to dangle your worm way off the end of the case mouth, you can do it with the MLR.
