"Fluted" lope

[jdpretorius]

Ek't nog altyd gedink fluted lope is sommer baie sexy maar kon nie een in die hande kry vir my Howa nie. Ek was ook onder die indruk dat hulle beter akuraatheid gee (en breër node bande) soos die van 'n duk loop maar met verminderde gewig en dan ook help om vinniger af te koel, lees toe nou hierdie artikel raak op faceplant... lyk my ek's heel die spoor buister gewees

"Tom Beckstrand in the 2013 edition of SNIPER magazine summarized some tests that Accuracy International performed to determine whether fluting a barrel affected accuracy. Here is an excerpt from that article.

One design change that resulted from AI’s exhaustive accuracy testing and development of the PSR [Precision Sniper Rifle] is the removal of flutes from the barrels. Engineers at AI decided to isolate the barrel flutes to see what impact they had on accuracy. The engineers attached a laser to the rifle’s receiver, another to the barrel, and a third to the scope. All three dots were zeroed at the same point, then they started shooting the rifle. They discovered that, no matter which fluted barrel they used, the dots would diverge as the barrel heated. The dots from the devices mounted to the scope and the receiver would stay in place, but the barrel’s device would manifest a point-of-impact (POI) shift. The POI shift from the warming barrel greatly diminished when they used barrels without flutes.

Engineers determined that the flutes never heated evenly, causing the POI shift. I hope the results of this test gain wide circulation through the sniper and long-range shooting communities to help eliminate some of the ignorance that surrounds the perceived advantages of barrel flutes. Flutes are great for shaving weight, but this is the first test I’ve heard that provided empirical data detailing what happens when the barrel is fluted. This should be the death of the “they cool a barrel faster, so they’re more accurate” argument, listed among flutes’ virtues. Our goal is and should always be to mitigate the effects of heat; fluting exacerbates it."

Baie interesant en dankie vir die inligting.

Daai is nou interresant. Dis goed dat hulle sulke ou onkunde uitsort.

maar dit bly maar nog 'n sexy look.
