Question Fluted vs. Non-Fluted

i know this is probably a stupid question but i just got my 10/22 a couple of months ago.What is the difference between fluted and non-fluted barrels, specifically green mountain barrels.

In firearms terminology, fluting refers to the removal of material from a cylindrical surface, usually creating grooves. This is most often the barrel of a rifle, though it may also refer to the cylinder of a revolver or the bolt of a bolt action rifle. In contrast to rifle barrels and revolver cylinders rifle bolts are normally helically fluted, though helical fluting is sometimes also applied to rifle barrels.

The main purpose of fluting is to reduce weight, and to a lesser extent increase rigidity for a given total weight or increase surface area to make the barrels less susceptible for overheating for a given total weight. However, for a given diameter, a non-fluted barrel will be stiffer and be able to absorb a larger amount of heat at the price of additional total weight.

The stock barrel that a 10/22 comes with is unfluted or non-fluted - means it is the same smooth sides from one end to the other.

Fluted means the barrel (such as the Green Mountain you speak of and others) has longitudinal (i.e. along the length of the barrel) dished out areas on the sides, much like many revolver cylinders are fluted. In each case (revolver cylinder and 10/22 barrel) it is to reduce weight by reducing extra material. And some folks think they look cooler that way.

IMO a fluted barrel, by reason of increased exposure of surface area may dissipate heat better than a non-fluted barrel. Buch like the "fins" on early subguns.

My take... If fluting was such a monumental advantage and one that provided such wonder improvements why don't more and more makes/models have them? Why aren't they the norm? Why are those applications where rigidity and cooling would be much more important using this, those such as LARGE guns (tanks, cannons, etc).
Everyone fires off the rigidity improvements and the cooling improvements yet I've yet to see any real world scenarios where a GOOD test and comparison was done that proved what everyone raves about. Have actually seen one of the barrel manufacturers give test results kinda disproving these claims.

Cooling effects...ok so there's a slight additon of surface area...how hot you gonna get that barrel so that it's hot enough to effect the performance? Heat effects would be so minute anyone THAT concern bout those effects clearly isn't using the barrel as intended, a target barrel. Maybe I'm missing something but target shooting, shooting for a group small enough to be concerned about whatever minute effects heat would affect, you wouldn't be shooting rapid fire or in any manner to create such a barrel temperature.
Weight...if the amount of material removed from fluting is THAT big of an issue the person should really consider investing more time, energy and effort into physical exercise. We're talking an ounce, maybe 2 depending on the barrel and fluting style. guess there's a lot of dainty ones worrying about that ounce.
Rigidity...Yeah, that's always been such a major concern...look at those cannons on tanks & ships...wouldn't they need rigidity? Nope, no fluting.

Now go and look at the top level target/match rifles, the olympic level ones. No fluting to cool them, no fluting to remove weight and no fluting to add rigidness. Hmmm, and those the epitome of .22lr target rifles yet they don't have this seemingly essential feature. Hmmm, maybe it's more internet "fact" than actual truth.


So...the differences between fluted and non-fluted... You can get a barrel with or without some flutes. Might save a whole ounce but figure the price difference and you're paying that difference for that ounce. Now if one's THAT concerned about performance, factor in that the fluting also can easily have a negative effect as the process can creature changes within the material adversely effecting performance. Bottom line, if you like the look and that look is worth the added cost over the non-fluted barrel, go for it. You're not gonna notice the difference shooting it.

I never said it was signficant, or even worthwhile Many "Machine guns" in the past had fins or flutes but in the long run it isn't cost effective and with swappable barrels cooling rate isn't a critical factor.

I personally can't find a space for one.

I would make space for a machine gun.

I have heard, and can't confirm, that the average .22 max's out velocity at 17" so a scope doesn't depend on sight radius, the longer barrel would be of no advantage. I think in a .22 if you need a couple more FPS you are shooting the wrong caliber anyway.

Just my .02
