    5R Rifling!

    My new barrel has 5R rifling that I picked because it seems to have some real advantages over the norm. And no disadvantages that I can find.

    What experiences have people had with 5R rifling?

    What I don't understand is why only a small percentage of makers offer 5R and those that do only list a few barrels with it.
    BCA, for example, lists 20+ 6.5 barrels but only a couple with 5R.

    If it's so much better why hasn't it caught on more and started to replace conventional (ancient) rifling?

    Edit: As a retired machinist I understand that it's not cut as easily as the older style, and that many people don't want to change from something that works "well enough". I wonder how many of we older guys just resist any change, period?
    Companies that button rifle their barrels could make the change easily. Making new mandrels for hammer-forging wouldn't be hard either.

    Some major companies seem to be going this route. I own a Ruger Precision Rifle that came with 5 R rifling.
    It shoots light out....

    I recently bought a Thompson Center Compass ( for less than $200 after a $75 Mail in rebate!! ) that also came with 5 R rifling. They are owned by Smith and Wesson. They guarantee a 3 shot group at 1 MOA at 100 yds.

    Before anyone buys a Compass....think before you do. They advertise it as an adjustable trigger and it is NOT. They had a recall and they took away the ability to adjust it but their marketing and advertising has not changed.

    The barrel comes threaded BUT not all muzzle brakes etc will fit. It is 5/8 x 24 and the barrel is so thin there is no shoulder behind the thread. My Little Bastard brake does not work. I called a lot of manufacturers and there are not a lot that will fit.

    It is what it is. cheap, and I knew it.....

    My most precise barrel is 6R. I dunno what is the correct answer.

    The advantage I've seen marketed is that the rifling does not directly oppose another rifling ridge, rather it is opposite a groove, which is supposed to cause less deformation and friction within the barrel as the bullet travels down the pipe. I can see where that could be true. OTOH, one match barrel maker has told me that neither they, nor any of their shooters, see any performance difference btw 5R and 4R. Personally I kind of like the 5R style but not really sure how true the benefit is...
    Some 5R's are also "polygonal" which means potentially even less bullet-mating friction...
    Barrel "goodness" IMO is probably more a function of the mfr, the steel, and their processes/QA, than the specific rifling style used.

    Is there any truth that bi metal ammo such as wolf may have more accuracy problems in 5r vs traditional rifling?

    I managed to get Bill Alexander on the phone once, and that's what he told me. My 16" AA shoots the stuff pretty well, but I don't have a 5R barrel to compare to.
