Bartlein v. Krieger

a lot of tony's records were set with button barrels , but he also set records with cut barrels as well ( check Super shoot record for the 2 gun ) common denominator was Tony Boyer , he was the best at getting the most out of his equipment no matter if it was button or cut , no need to post lists ,just go to the IBS or NBRSA website equipment lists are there since 2010 kriegers and Bartliens are the most popular.
original question was Barrel life
the real answer is when they can no longer win at the match they are done , downgraded to test bullets and practice , needs to be able to shoot a teen agg to go to a big match that could be anywhere from 400-2500 rounds and maybe more on a really special one ,very rare
as for button vs cut , all things being equal ,material ,dimensions and land/groove percentages you can expect the same round count, barrel maintenance plays a significant part
hope that helps

Sierra is looking for a far different resolution than that needed in sbr competition , I would guess that a barrel would be just fine for anything else long after it has become non competitive for sbr
 
Back in the old days , when I was looking to get an M24 built , I had this discussion at length with several knowledgable companies . Sierra and others . They all said the same thing , cut rifled had a measurably longer service life . The original barrel supplier to the US Army's M24 SWS was Mike Rock and his barrels were single point cut rifled 5R with an Obermeyer Match chamber . Once the M24 SWS had won the Army trials , manufacturing en mass went to Remington . Not because it was better , but because it was much faster to get service replacement barrels .Some of the original M24 "magic" was lost . That's not to say that hammer forged or button rifling is bad , not at all . However , a top quality cut rifled barrel by the top makers has a proven track record . When Accuracy International was awarded the sniper rifle contract for the MoD in the UK L96 , they sought out several of top cut rifled barrel makers ( Mike Rock and others ) and made every effort to buy them out or secure all of their production exclusively . I ended up with a Mike Rock barrel ( I was very lucky ) and to this day , I've not had a better barrel . As a side note , at the time , the Canadian National PRS championship was won with a Mike Rock barrel that had 9000 rounds through it . I shot this rifle personally and at 9000 rounds , it shot better then I could shoot it .
 
I have no experience with krieger but do have 1 bartlein and a buddy has 1 bartlein as well. Both are hammers. Mine only has 500 ish and my buddies is in the 1500 ball park range. I do have a few benchmarks as well and they have all been fantastic as well. I have the button benchmarks.

I now primarily run KS arms barrels thoigh which are cut, trying to support Canadian. Mike over at KS has incredible service, and a wicked product! His barrels shoot with the best of them no doubt
 
with the 6ppc from what i gather is 800 to 3000 rounds, one guy i shoot with is on his second setback and about 3000+ rounds total on his kreiger barrel, he shoots fairly light loads though.

I killed a bartlien after about 2800 rounds shooting hot loads in a 7 twist 223...... it was insanely accurate until it wasn't lol.

I've personally gotten to the point where barrel life is a mute point for me with the way everything is going for cost of components...... i need to shoot itty bitty groups all day and when the barrel is done ill put it in garage.

someone did mention HWP earlier in this thread, I now own 3 of them and will probably only buy from them until something that is proven to be better comes along
 
To answer the original question, I asked Frank Green of Bartlein Barrels if cut-rifled barrels do have increased barrel life.

He says yes. All the ammunition makers have seen at least a 15% increase in barrel life on their test barrels over buttoned rifled equivalents.

So there you go. More data that suggests that cut rifled barrels have a bit more life to them then buttoned.
 
This may be apples to oranges hearsay type data, need to test the same lot of material and make sure the land/groove ratio is equal and of the same configuration, typicaly they are not in cut vs button barrels
