Krieger 5R barrels ???

Virtually every one of my most accurate barrels I have had, have been Krieger 4 groove "conventional" rifled barrels. That is MY personal experience. However, having said that, I have friends who I know are EXCELLENT shots that have very successfully used "5R" barrels from the custom barrel makers. We all tend to lean towards what has worked for us. I have had 2 .260A.I.'s (and a 3rd on the way) that have been from Krieger with 4 groove conventional barrels. They have been the MOST accurate barrels I have ever shot>>period! So, for me, why would I change? I won't. Does that mean that 5R barrels do not shoot? Heck no, they have and they do! As for me, I will stay with what works BEST for me..
Same here, my most accurate barrels have been 4 groove Kriegers. Takes a bit longer to clean than a 5R. My 5R's are not bad at all but seemed to be more sensitive to seating depth / took me longer to get loads for them.
On the other side of the coin.
Yesterday I shot a 1/4 MOA 4 shot group @ 600 yards with my buddy's varmint rifle, yes, I said "varmint".
It is a highly tuned 700 LA chambered in 6mm Remington with a Bartlein 5R barrel.

If I remember right Krieger was one of the last to offer a 5R barrel after the shooting world went crazy over them {translates to "somebody won some big matches with a 5R"}. Krieger tried for quite a while to get away with not making them, but the competition got too stiff and they had to cave to get in on the then big market for 5R's.
I definitely remember when the world first lost it over 5R barrels...Krieger had a big write up on their website that explained how they made a few for test purposes and were unable to conclude one way or another that there was any advantage whatsoever and so they made the decision to not offer 5R barrels "at this time." They must have realized at some point soon after that they were losing too much business and opted to go ahead with throttle up and make the barrels.
A good barrel is a good barrel and I have tried every configuration of rifling available put in the tube every possible way...I cant tell any difference, accuracy, cleaning, fouling or break in. I believe that the idea one barrel type is better than the other is a religion. About the only thing I can say about different barrels has nothing to do with the rifling type...lightweight contours walk less if they are single point cut rifled.
All this said...my most accurate rifle is a four groove conventional Krieger AMU contour on a pre-64 Model 70. Needless to say...I don't shoot benchrest.

msinc, the above is what caught my eye, in your post. Care to comment further? It seems to excuse what preceeds.

I've only had one 5R Krieger barrel and i didn't see any difference in accuracy compared to the 4-groove Kriegers i've had, they all shot well. Nowdays i shoot 5R Bartlein barrels and have good luck with those also. I've shot a couple 4-groove Brux barrels also and they were very accurate as well but a tad slower than the Bartlein and Kriegers i've had.
Certainly, and I do apologize if I left you hang. That was not my intention. Single point cut rifling is the least stress inducing method, therefore barrels made in this manner should walk less as you shoot it and it heats up. As opposed to button rifling, which could be described as a snake swallowing an egg or cold hammer forged which, just as the name implies, is just that...beating a pipe over a mandrel until it takes on the shape of a barrel. This has to be one of the most stressful methods. Barrels are of course "stress relieved" but this doesn't necessarily always take out all of the stress that gets put in. I would say that the theory of not adding anymore than you have too yields the least stress in the finished product.
More likely to cause reamer chatter when chambering. Otherwise I haven't seen any difference on target.
I had one for my first 284 shehane barrel. It nearly caused me to forget running a 7mm in f class. The thing was a down right lemon. Sorry for being blunt but it was barely good for a tomato stake. It just would not hold a load together at all and patches would barely cause a rod to spin down it. I gave up on it and ordered another brand in conventional rifling and had no problem, in fact cleaned the target at 600yds with my first ever shoot with it after load development. Since then I have had 2 others of that same brand and all are as accurate as each other. Havent had a great run with kriegers myself apart from one 6mm in a dasher that shot lights out at a very long way. But losing 50 thou in throat erosion over 500 shots didnt impress me either.
Have resisted going to 5r barrels again but Im tempted to steer towards a new bartlein for my upcoming saum build. I hear 9 twists cut barrel bartleins are stabilising the 183 sierra and proving to be very accurate.
