From another thread it looks like fluting a HBAR reduces the weight somewhat, improves cooling, and looks cool. Are there any other advantages or disadvantages to fluting?

For a rifle that is used at the range or in a class firing maybe two hundred rounds per session, is fluting going to provide a noticable difference in performance?

no

I read some mind numbing info on barrel fluting on tactical rifles over on snipershide.com a while ago. Lots of opinions on both sides as I recall. for such few rounds I can't see it making any real difference for you. I do agree with you it does look cool. If money is no object, go ahead.

Regards,
Gary

Thanks for the good input.
It sounds like there is no real measurable advantage so I'll pass on the flutes and find another way to look cool.

i would pass onflutes. they cost money, look too pimp, and stress the barrel from the machining op. they do aid cooling and result in a stiffer barrel per unit of weight, but taking any given barrel and cutting flutes makes the barrel less stiff.

Is cooling off the barrel really something to be concerned about? (If you are shooting any place except from a bench that is)

I'm no marksman, so I can't see my own accuracy being affected more by barrel heating than by say, bad eye sight or just plain old bad sight alignment.

They are coming, the SAW version of the XM8 used them.

You may want to read this. I agree with the FAQ long as the setup is strong and chatter free and the tooling is sharp because if you chatter or your cutter starts to tear instead of cutting properlly you add some compressive stress.

Since your question was most likely meant as a rhetorical question I'd bet it's 5 more than you thought would be listed :)

I was just giving you a bit of a hard time. Finned barrel, yuck it becomes as whippy as the minor diameter but it's cheap. The old engineering adage of "fast, cheap, and good, pick any two" needs to be mentioned in any discussion about fluted barrels.

Well my Bushy Varminter has the fluted HBAR and is definetly not wanting for accuracy!
