ANY 6 BRA BARREL LIFE NUMBERS?

[ngb1787]

Wondering if anyone has shot out a 6bra barrel yet. Approx Velocities of 2985.

Wondering if anyone has shot out a 6bra barrel yet. Approx Velocities of 2985.

Kind of hard to quantify. If I am an anal 1000 yard shooter and will only accept perfection, my barrel life will be significantly shorter than a guy who does not care as much. I will watch the answers here because I have ordered a 6 BRA and I am trying to brace myself for replacement barrel cost. It would also be interesting to know how the barrel life compares to the straight BR and the 6 Dasher.

 

[Dusty Stevens]

Itll be better than a dasher but nit as good as a 6br. Itll be better than a 243. Just compare powder burned and what you usually get that fits your accuracy. No matter what case it is if youre burning Xgr of 4350 pushing a bullet at X velocity its going to be the same as another ctg doing the same. Move the numbers one way and it gets better or worse. And according to your needs it could be way more. Like my ppc barrels that are shot out at 800rds still shoot 1/8” so theyre good for another 1000rds at a prairie dawg. So no definite answer

Just posted the below as I didn’t see your thread. As I was asking pretty much the same, will delete my thread.

“With my 6 Dasher I have only been shooting 32.4gn of Varget & 105gn Berger bullets. Never change the load, just use a tuner. It seems to me the barrel life to be able to regularly shooting 1.5-2.5” 5-shot groups at 500 yd in light winds is in the 400 round range. Does this sound reasonable? Mostly concerned about consistent accuracy. Do you see any/much difference in the barrel life span by brand?

Response to Ben's post (not 6BRA)
6 Dasher 1.5" five shot groups at 500yds is easily doable in good conditions much higher than 400 rounds on a barrel. All barrels behave a bit differently but as the Dasher's throat erodes you need to adjust your tune. I don't use a tuner but know I need to + up my powder charge every few hundred rounds to keep the gun in tune. One of my Dashers just went over 1,000 rds, has .050" of throat erosion from new and it is still shooting pretty good. It is capable of 1.5" five shot groups at 500yds and I will take it to NBRSA nationals as either my primary or backup rifle.

Good shooting

Rich, thanks for the reply. For now this barrel is parked on the shelf. Will spend some more time with my borescope and get some additional feedback with different sets of eyes. The SD on the ammo for this barrel has been adjusted at least twice.
An easy fix would be nice,
Ben

I notice no body talks about set back. I had a great barrel, a Brux that was set back 3 times, and had over 3000 rounds through it and still shot in a 1/4 min. without the need for wind flags.Great barrels I will shoot till they are less than 24" at 1000, Then they are great varmint barrels. They don't quit, just because they are set back...... jim

Jim, little slow to respond but I am interested in your set back process and frequency.

Good advice thankyou... I will be setting back a 6BR Barrel I have now that otherwise wouldn’t have..

ask @pat fulghum

He just put one away after a very successful F-open campaign. Something like 3k rounds...

Yep... put one to bed (Krieger HV) at 2900 rounds. I never measured total growth ...

It started out at .001 every 100 rounds, but I stopped measuring it after about 500.

But I do know that I had .065 at 2300 (Yikes ), when I had to switch to Berger 108s as the hybrids were just hanging on to the brass.

I put a new Bartlien 30" on in Jan and it is doing much better. I still might just set the Krieger back for fire forming. To be honest I wish I would have just put the new one sooner. ​

Thanks for sharing, that's a good number for a 6mm. How was it shooting when you finally pulled it? Did it lose much velocity and/or did you add powder to compensate?

I'm assuming you chased the lands from your above comments. You have a 104 freebore?

How was it shooting? Still good but about 1 in 60 shots would fly a little.

New barrel has dropped 2 points in 3 matches with a nice X count.

Thus my statement “I wish I would have done it sooner”.

 

[Dusty Stevens]

A barrel will last thousands of rounds. The question you should ask is how much am i spending to go to matches without a fresh barrel? Pat could have shot that barrel another 4000rds but having a fresh one on there i bet he wished he would have changed it 1000+ rds ago. Its all in how well you want to do and how much you value winning.

This is something I see, many times the best groups from barrels are after it's rechambered..

Ray, You hit the nail on the head, Great barrels last a long time. If you take care of them...... jim

I. really think your numbers are a little out of line. I happen to know a score shooter that took a 30 cal. barrel to the national with from 7000-10,000 rounds through it........ and won....... set records. Great barrels don't die easy.... jim

 

[Dusty Stevens]

a slow twist 30cal barrel is immortal.

 

[johara1]

I also seen them burned up with less than 3000 Rds. I see the The barrel maker that that Dean had is no longer making them, but the ones that burn up fast are....... lol...... jim

Jim I had my wife's rifle set back three times and the last time she won H.G. overall and got in the Hall of Fame all in one year.
