Which is better and why? Is fluting worth an extra $100 on a custom barrel?
Which is better and why? Is fluting worth an extra $100 on a custom barrel?
If you take a barrel before you flute it and then flute it the UNFLUTED BARREL is stiffer.
However if you take 2 barrels the SAME WEIGHT one is fluted and one is not the Fluted barrel is stiffer .(IT DOES NOT GAIN STIFFNESS FROM THE MACHINE PROCESS OF BEING FLUTED)
CONCLUSION ON BARREL FLUTING....
When comparing two barrels of equal weight, length, and material but one is solid and other is fluted, the fluted barrel will have:
A larger diameter
Greater stiffness
Vibrate at a higher frequency
Less sag (vertical end deflection from the barrel's own weight while in a horizontal shooting position)
Fluting a solid barrel will:
Reduce its weight
Reduce its stiffness
Increase its natural frequency of vibration
Decrease its sag.
Reducing the weight of a barrel by fluting makes a stiffer barrel than reducing the weight by decreasing its diameter.
A shorter barrel of the same section, solid or fluted, will sag less and vibrate at a higher frequency
A fluted barrel has much less rigidity than a plain barrel of the same diameter, and more rigidity than a plain barrel of the same weight. But those comparison barrels are not, cannot, be the same. The plain barrel of "same weight" will have a necessarily smaller diameter than the corresponding fluted barrel. The material in the fluted barrel is arranged, due to its greater major diameter, more advantageously to resist bending than the plain barrel's material. So you can have your cake or you can eat it, but not both!
