Rifling

Thanks for the heads up that gave me the answer to my question.
Didn't mean not to personally answer your question. There are so many "Opinions" on different Rifling. There are many Posts on this subject here on LRH. If you are looking at "Accuracy" many championships are won on Cut 5R along with Button. We shoot both and have had barrels that shoot in the same hole.
Now just speaking about Rifling you have to also look at the Manufacture of the Barrel, the Process, the material.
As Mikecr stated with Cut Rifling has less STRESS during the "Cutting" but when doing the Button there is a HEAT Treatment to relieve the STRESS.
I could write a few pages of the processes and the history, but it's already in many posts before this one.
 
Take notice that twist rates when accurately reported by tge manf on button rifled barrels. You will not see that in cut barrels unless it's done on purpose. Cut rifling allows tighter controls of tge dimensions and flexibility of changing configuration of those dimensions. Take a Bartlein. If they want a 8 twist they will get exactly an 8 twist. Button it might be anywhere from 7.8-8.3. Lots of winners over the years from both technologies but I think cut rifling with modern CNC controls allows for the tightest most consistent tolerance and largest flexibility in configuration.
 
Is cut rifling really better than button rifling, if so why
I like PVA's stance on this issue: https://patriotvalleyarms.com/barrels-cut-rifling-vs-button-rifling/ "I" do not think this can be easily quantifiable, esp. for the average end-user. I lean more toward the process owner and the quality of equipment/technology, the material used, and expertise, not the process. I have had both, with positive experience. I have two Lilja barrels (pull button - https://riflebarrels.com/about-lilja-precision-rifle-barrels/) in 3G that are simply a pleasure to shoot, accurate, and hardly foul.
 
A hummer barrel is a hummer barrel.....it could be cut or buttoned and it could have any manufacturers name on it. That said "I think" cut rifled barrels are more consistent and true to the twist.
 
Before I started turning barrels I was almost exclusively using Brux. I believed cut was the best. When I got to the point of doing my own work, I started experimenting (needed experience) and I've come to the conclusion…there are good, average and bad barrels. I think some manufacturers processes can produce more good ones say per hundred than the other but todays technology there just aren't many bad barrels.

I used to shoot benchrest (300-600y clays) and in I don't know how many barrels I've only had one bad one…it was a Krieger and I'd buy another one tomorrow.

There are differences in the process but the target don't lie. A lot of short range guys use both barrel types and without zero doubt, those guys are shooting the most accurate stuff in the world…if there was an advantage, they'd all be shooting that barrel and rifling type.

Saying all of that, I ordered 3 Brux's yesterday but I've also ordered Carbon Six within the last month too ;)
