more to follow soon. I am definitely learning more and hopefully so will others

Flow Form Rifling is a newer method used by forming the grooves and lands in the barrel as well as the outside of the barrel at the same time. A barrel blank is flow formed over a special mandrel containing th exact reverse image of the inside of the barrel. The blank is rotated in both...

broached rifling is the process of cutting all grooves at one time with a special progressive bit almost like a tap that threads a hole for a screw. Broaches are very expensive-too much so for the independent barrel makers. Mostly governments use them in war-time production facilities. Many...

Cut Rifling is the process of cutting one groove at a time down the bore of the barrel using machining equipment. The major advantage of cutting the grooves rather than hammering or ironing them into the bore is that there is no stress introduced. Special twist rates and groove depths present no...

Button Rifling is using a highly-polished carbide "button," about half an inch long, tapered at both ends and containing the rifling in reverse, is silver-soldered to the end of a smaller diameter rod and pulled through the bore. The grooves are literally pressed or "ironed" into the steel. It...

Hammer Forge Rifling is a process used by most large manufacturers like Remington, Winchester, Ruger, Sako and Steyr. It involves very large and expensive machinery that can take a nearly 2-inch-diameter bar of steel about 12 inches long with a hole through its center, and by hammering it...

Thanks Art

The grooves are the spaces that are cut out, and the resulting ridges are called lands. Most rifles have a minute gain twist if not a higher one due to the fact that a decreasing twist down the length of the barrel is detrimental to the accuracy of the projectile.

There are various ways to rifle a barrel. The most common ways are 1. Cut Rifling (hook rifling) (single point cut rifling) 2. button rifling 3. hammer forging 4. broached rifling 5. flow forming brief descriptions to follow.

Rifling is the process of making spiral grooves in the barrel of the firearm. It serves to spin to a projectile around its long axis. This spin gyroscopically stabilizes the projectile, improving its aerodynamic stability and accuracy. Rifling is described by its twist rate, which indicates...

Stress relieving the steel of a barrel is extremely critical in the manufacturing process of the barrel. Machining induces stress in parts. These stresses can cause distortions, cracks or bends in the barrel which must meet incredibly fine measurement specifications. Heat is used to break the...

First of all, accuracy isn't particular to the specific type of steel that a barrel is made from. An extremely accurate barrel can be made of either a 4140-type chrome-moly or 416-type stainless steel. The chrome-moly is less expensive to obtain, much easier to machine, and requires more care...

I will do the legwork because I need the educating. I will post the answers to my questions for anyone to add to or correct. I hope that it will benefit others out there that are curious to understand their rifle a bit more.

why do I want the bore of the Barrel to be "smooth and shiny!"

Why do some barrels have thicker walls than other barrels? What is the difference? What is the difference between 2 barrels made the exact same way, but one is more accurate than the other?
