Originally designed as an AR-15 round, the 450 Bushmaster is seeing an increase in demand in states like Michigian where shotgiun only deer hunting zones are being opened up to a wider variety of weapon types. Ruger has released a bolt action American Ranch Rifle in this large .450 caliber with hopes of taking advantage of these hunting regulation changes.
The new Ruger .450 Bushmaster American Rifle Ranch is the third member of the American bolt-action line designed to fire AR-15 semi-automatic cartridges, including models chambered for the .223 Rem. and .300 Blackout. The 16.12″ cold-hammer-forged barrel is free-floated and has a muzzle threaded at 11/16-24 TPI. The muzzle is then fitted at the factory with a specially designed muzzle brake secured by an adjustable barrel nut in place of a crush washer.
As is the case with most high quality Ruger bolt action rifles, the .450 is fitted with an integral Power Bedding block system which is responsible for much of the rifles accuracy in additon to the adjustable trigger:
The Ruger Marksman single-stage adjustable trigger provides the feel and performance of aftermarket upgrades, which are often fairly expensive to buy. An Allen screw mounted to the front of the assembly (which is exposed when the action is removed from the stock) can be used to shift the trigger pull weight from 3 lbs. to 5 lbs. This particular trigger was set to 4 lbs. 4 oz. when it arrived, and exhibited a clean, crisp break with almost no overtravel. The safety lever found in the center of the trigger, much like that of a Savage Accutrigger or Glock pistol, locks the trigger and prevents it from cycling until it’s properly depressed by a finger tip.
The price tag on these well built, american made rifles is surprisingly affordable with scoped models selling in the $450 range. Granted they aren’t walnut stocked show stoppers, but for the money they offer excellent accuracy and dependability with some serious stopping power. Finding .450 rounds can be a bit of a challenge with only a few ammunition companies offering them at the moment but this problem should be short lives as the popularity of this cartridge grows.
