Bore life - 6BR... vs dasher, XC, or 47 ?

[65BR]

Anyone have any ballpark numbers?

Thanks.

From having a 6br and what Ive been reading on this site for a while, it seems the br and the dasher are close but the xc and 47 are a little less. Maybe someone with one of them could chime in. You should hopefully get around 2000-2500 out of a good 6br or dasher barrel.

I would hope you could get a LOT more than 2000 to 2500rds out of a 6BR!! I was getting 2300 to 2400rds out of a 260 using it in comps. My current one has close to 3000rds through it shooting 123s close to 3000fps.

As far as the 6XC I had 2300rds though mine and it was still a hammer but I wanted more juice out of it so rechambered it to a 6SLR and shot it another 800rds then made a 284 out of it.

I just shot out my 6BR, 2700 rounds and it went from .2" to 1" groups in about 200 rounds... so 2500 with good accuracy and now it's just a nice varminter...

Sorry Guys you are correct. It would depend on what type of accuracy your are looking at. I gauge mine for tactical shooting and only require .5 or under for my guns. SOoo......... I stand correted!!

I don't think you can put a number on it, but the barrel sure will let you know. I have one old Kreiger fire form barrel with over 2500 rds. through it and it still shoots well. it was set back twice and it will shoot in the ones @ 100 and won a 1K match with a 10 shot 5" group. I have a new Kreiger thats a fire form barrel, it never did shoot. i guess these are extremes but too put a number on it you can't....... jim

My Dasher's current Bartlein barrel (8 twist .236" bore) went from ho-hum .2s to oh-no .4s after 1,140 rds. Cut off 1" and rechambered and it's ho-humming again.

Already have a new Douglas tube ready to ream in Jan/Feb, though.

Killshot, was it a 5R or 4 groove ? Did you recrown it?..... jim

 

[Killshot]

Jim, it is a 5R and we just kissed the crown, didn't do a cutoff.

It's been a good one, never really copper-fouled. The throat cracked up, but l do run it on the fast end and shooting long F-class strings in the California heat doesn't help things.

Thanks guys

Killshot, I will try a other Bart. 4 groove but after it's froze....jim

I agree with Dave Berg. Every 6BR barrel that I've had lost it's edge at about the 1200 round mark. That's for a competition rifle where .1's are necessary to place in the top three at matches. If you want to win you have to pay the Piper.

How many rounds can you get and still hold .5moa or under?? Thanks guys!!

I am on my first dasher barrel and at 1800+ it is still shooting well under 1/2 MOA. That is shooting fclass 20+ shot strings
