One thing I noticed, is that all the manufacturers use straight flutes, and I'd guess that a spiral fluted barrel would have more lateral deviation versus a straight fluted one.
So, I just emailed Kampfeld to see if he has any straight flute options that can remotely approach the significant weight reduction of his aggressive spiral fluting. I wouldn't hesitate if it was 300, or maybe even 400 yard rifle, but I want it for 500, where I'd like to have 1/2 moa accuracy as I don't like taking chances...
I'd appreciate any thoughts on this, and any sightings of sub moa spiral fluted barrels.
- lastly, looks like Karl can cut about 4 ounces off a 20" barrel (deep spiral cuts), although my 22 creedmoor barrel has a lot more excess to play with.
*Edit. This thing is so muzzle heavy with the crazy light stock that I'm definitely going to have Kampfeld do a very aggressive fluting job, especially since I'll be adding an Ultra 7 to the end.
If it was a 308 or bigger bore cartridge I'd highly recommend going with 16" to help balance the gun, if you want a feather light stock that is.
