With the recent changes in the regulations for deer hunting firearms in Michigan, Ohio, Indiana, Delaware and now Iowa, Bear Creek Ballistics is producing a custom 450 Bushmaster rifle/ammunition package that is absolutely devastating on game. The custom ammunition developed together with these rifles will consistently give 1″ or smaller groups.  The 240 grain HV all copper bullet leaves the muzzle at 2,590 fps generating over 3,400 ft-lbs of energy!

The Action

  • The Howa 1500 action is a great all around work horse of an action. This action is manufactured with extreme tolerances that provide the operator with ultra smooth feeding and shooting.

Stock Options

  • HS Precision is the stock this rifle comes with. The color is green with black webbing however HS Precision does make alternate colors; if you want to choose an alternate stock color or already have one, you can send it in to be built with the rifle.

The Barrel

  • Douglas XX premium grade stainless; 1:16 twist; #5A contour.
  • We have found a 23″ barrel to be the optimal length for the 450 Bushmaster cartridge.
  • One of our custom muzzle brakes come with the rifle package and is fit to the barrel. If you do not want the threaded muzzle with muzzle brake, we can machine a target crown instead.

The Trigger

  • The trigger supplied with this rifle is the stock Howa 1500 trigger which is set at a crisp 2.5 lbs.
  • Timney Trigger upgrade is available.

Barrel and Bolt Fluting

  • Fluting of the barrel and the bolt are available above in the selection list. Straight and helical full length fluting is available for the barrel. Fluting of the bolt is only available in a helical pattern.

Forearm Picatinny Rail 

  • An option that we started to offer is a picatinny rail that is bolted to the forearm of the stock, this allows the operator to attach a bi-pod or other accessories to the front forearm of the rifle as well as having a spot to attach a sling. Many customers enjoy attaching an Atlas Bi-pod to this rail due to its rigidity and light weight.

Optics / Scope Mounts

  • The majority of our rifles are built using Leupold scopes using the CDS turret system.  We prefer to use Leupold VX-3i, Leupold VX5 and VX6 scopes.  We have built many rifles with these scopes with great results.  If you choose to go the route of the Leupold CDS system we will match the drop of the ammunition to the CDS turret cap.  We will build the rifle with a customer supplied scope as well.
  • We believe Talley one piece scope rings are the best combination of price and performance.  All scope rings are assembled to the receiver and lapped to common center line to eliminate manufacturing tolerances and prevent inducing any torque in to the scope tube once the scope is assembled to the receiver.


  • Capable of using our custom 240 grain HV and standard 450 Bushmaster ammo.
  • 1 MOA accuracy guaranteed
  • Excellent accuracy out to and beyond 300 yards.
  • Ballistic Trajectory with Bear Creek Ammunition 240 HV bullet (2,590 fps): +2″at 100 yards; -4″ at 200 yards; -14” of drop at 300 yards; ammunition will retain 1,000 ft-lbs of energy at 400 yards.
  • Weight – 8 to 10 lbs.


  • Shipping of the rifle is available, we offer a shipping package with the rifle that covers: Shipping costs, insuring the rifle for the full value incase of damage, and a Pelican Vault hard case. (Please call to purchase)
