Barrel Selection & Contours

Van Dyke Rifle Designs offers only the finest world class rifle barrels.  The barrel makers we use are highly-focused experts with many years of experience.  We prefer the use of Shilen, but will offer Krieger, Lilja or other barrel makers if the standards are acceptable.

We use only select match grade which will cost a little more but is a small price to pay considering it's place in performance.  The barrels are masterpieces  that historically have been proven throughout the world in virtually every competitive rifle shooting event.

All barrels are meticulously chambered by precision JGS reaming tools with live pilots to exacting chamber tolerances.  Our tolerances are held to very tight minimum dimensions so that factory-made ammunition can fit closely without robbing accuracy.  Holding the cartridge more concentric to the center bore enables the customer to achieve good accuracy with a variety of factory loaded ammunition choices.

Factory ammunition has improved somewhat over the years as an attempt to offset manufacturing fallacies.  This improvement can ideally be realized in a custom rifle design and is profoundly noticeable at the range in a good rifle that is properly chambered.

Contours

What size barrel will serve you best? The information below will give you an idea of the size and weight of every Shilen barrel contour. Dimension "C" is the muzzle diameter at dimension "F", which is our suggested finish barrel length.
