I have one on a Remington 243 cal. made by a Russian company SPR18 and all I can say it shoots.
I don't the 11mm rail on the top of the action for scope mounting :I had to cut the stock and change the recoil pad to get a shorter L.O.P.
Can't imagine you could guess how it will do only by looking at the
If it was easy, anybody could do it.
just wondering if any one has any experiance with spiral flutted barrels do they shoot strait or when warm will they start to walk the bullets around the target
it looks real pretty but will it shoot strait ?
Anschutz done that My buddy had a 22 mag and at 50yds 10 shots were near same hole dont know on a hi power but any will drift if barrel gets to hot rick
I've got a spiral-fluted E.R. Shaw barrel on a 6.5-06, and it shoots like nobody's business. I've never really gotten in 'warm,' as in firing 20 rounds as quick as I can load them, but for a hunting rifle I'm quite pleased with it's accuracy.

I had Shaw rebarrel a Model 70 stainless that had a typical mid 90's (at least in my experience) junk Winchester barrel on it to a 257 Weatherby 26" 2.5 contour and had them spiral flute it. Shot great, never had a walking problem. The theory is, and it is just a theory that the spiral fluting will help the rotational torque from the bullet traveling down the barrel and being spun by the rifleing. Whether or not the barrel shoots IMO has litte to do with the fluting. I only had it fluted for weight purposes.
I hate to be pedantic but that is HELICAL fluting.
i had never heard of or seen a barrel like this untill the boss asked me to set the mill up for it, it surprised the hell out of me as i am only 3 months into my first year of the apprenticeship.
Spiral milling is the same except you use a rotary table geared into the cross feed.
five flutes two passes per flute 45 minutes per pass
used two old barrels that were shot out and damaged as practice trying trying different things to get everything set up just right, learned a lot about milling but spent a heap of time standing there just watching the machine do its thing.
Cutting straight or helical flutes is very simple on a cnc mill that has a 4th axis.
Both ends WHAT a player
this fluting is spiral fluting because the barrel is tapered and the fluting changes radius making it a spiral
if the fluting is done on a bolt or barrel with no taper and the fluting is parallel then yes it is helical fluting
the boss heard back from the owner of the barrel after initial sighting in it reliably shot .8 moa
