Still been having some issues with my 6xc not shooting as well as I expect and I happened to be perusing the kreiger website and I noticed they don't recommend 5r rifling for any 6mm barrels. Now that's not to say it can't be done but I'm wondering what people's experiences are with this combo good or bad. Mine is a Bartlien 5r, 1/7.8. 28 inches long on a Remington action. It shoots 1/2 moa but I struggle to keep it there and I figure it should be doing better. Any thoughts?
6mm bullets and 5r rifling?

Have you tried different bullets? My 6BR 4-groove Shilen would not shoot 87 gn V-maxes at all. I switched to Berger 80 grain FB Varmints and now its 1/3 moa or less, and getting better as I get better.

What twist barrel is that Shilen if I may ask?

John Whidden seems to like 5C barrels for his 243 Win:

I believe that 5C and 5R barrels are essentially the same except the 5C name is used by Broughton for their button rifled barrels while Krieger and Bartlien use the 5R name for their cut rifle barrels.

Mike,
It's a 1:8 twist, 24 inch, barrel nut DGV action on a B&C Medalist stock. The best I got out of the 87s was about 2 inches at 100 yards! Switched to the Bergers and now it's a tack driver (in search of a driver). I'm using about 27 grains XBR (46 1/2 clicks on a Harrels) and CCI 450s in Lapua blue box (.270 neck chamber, loaded round is right at .268). Prolly too much info, but I hope it helps.

Need to correct that statement. Kreiger's website does not say that. It only applies to the small light 6mm bullets (i.e. for short range benchrest with 6mm PPC the 5R rifling does not work as well as a conventional 4 groove). Krieger's website does not indicate anywhere that faster twist 5R barrels shooting heavier 6mm bullets presents any accuracy or other issues. Krieger won't make a 5R 6mm barrel in any slower twist than 9" for that reason.

I have a bartlein 1-8" 5r on my 6 dasher and it shoots great. Would definitely do it again.

No, Roger. That's an F-Class MR63-FC target shot with an F-Open rifle. I've seen some sling shooters that can do that on their target, too.
Steve,,thank you...Im hoping to get healed up from my broken neck somday and try F class ,,,,right now I cant get up n down from the ground easily,,,,have to shoot from a bench,,,I have a cupla rifles that should be competitive if I wuz able...hahah....that is good shooting on your part,,,I realize you cant dump the 20 shots like benchrest,but have to wait on your puller,and hope the wind doesnt change!!!,,,Roger

I live in new york state,how unfortunate !
I have a 1 in 14 on a semi trued remmy I built with a new shilen 1in14 ratchet twist(their name for canted rifling) 6BR and with arnette 68flat base bullets shoots quite well with ragged groups the norm when I do my part.I disagree that it wont work with a 6mm bore.It also cleans up so easily ,it takes about 5 minutes and ready to go again.
I can't speak as to the Krieger 5R 6mm, as I simply don't know, but I have used several Broughton 5c barrels in many different twists and calibers, including 6mm with light bullets....all I can say is that whatever reason Krieger has for not using it must not apply to a Broughton, as they have all been excellent shooters!
Have you tried boattail and flat base bullets??? There are barrels that simply won't shoot BT bullets.
Yes. I find it rare that a good barrel won't shoot both RESPECTABLY, but have seen barrels that simply hated a given high quality bullet...some were flat based too. I'd love to know why. ???boltgunluvr said:

I have 3 6XC's 2 Bartlein 5R and one Kreiger 4 Groove, all shoot 1/4 or less. Last group was .163 not bad for a target rifle. Shoot a 16X cleen at Cadillac with my Bartlein, I personally think that they are the greatest thing ever made.
