Satern makes barrels for the Savage in 45 Raptor. I've built an AR in the Raptor and couldn't get a bigger grin on my face everytime I pull the trigger. I would be careful in those states that are allowing the straight walled cartridges but specify which caliber. The 45 Raptor brass is marked 45 Raptor not 460 S&W even though other than the difference in rim, they are the same. Michigan doesn't designate specific cartridge, just case size and minimal caliber.
