bad barrel?

[Stan Taylor]

i am going to do that i think. thanks

I personally think you should have done that first no pun intended.

 

[ridgeway]

Yes, delete this thread and call them ASAP. They WILL take care of you....

 

[jackieschmidt]

I personally don’t care what a barrel scopes like. Either it shoots, or it doesn’t.

I have been shooting Benchrest since the mid ‘90’s. Ever since it was concocted, I have put nothing in a barrel but Butch’s Bore Shine. Even after Butch’s untimely death, it stayed the same.

But then, I shoot cut rifled Kriegers and Bartliens.

Sooner or later you have to decide how many good bullets are you going to waste on a bad barrel.

I don't really see anything in your pictures that is worrisome. Barrels that look a lot worse *cough* savage *cough* have shot very well.

Have you inspected your crown very carefully? Did it shoot well at all in the first 200 rounds, or has it always been a poor performer?

In the last picture there seem to be some marks that run a little diagonally across the top of the lands, not exactly in line with the rifling direction.

Are you using a bronze brush? If you are is the cleaning rod handle turning freely.

I have had a cleaning rod handle that became a bit stiff and the bronze brush wouldn’t spin completely with the rifling and the brush would skip across the lands. It was a 5r style barrel however.

Either way clean all that carbon off then take some more pictures for us.

to answer the questions.................the barrel has not shot well from the beginning, i have inspected the crown which looks good, and i have never used a brush of any kind in the barrel.

I'm going to stay away from the brush debate.

Here's my feelings, which align with jackie's: the time and money spent chasing a barrel that isn't working for you can quickly exceed the cost of replacing it. I drive 75 miles out to my shooting spot and back, and I shoot 50 rounds through each rifle while I'm out there. That's about $30 in gas usually and $30 in ammo per gun per trip. If I put in cleaning and target/range supplies, wear and tear on my car, and also consider the ~2-3hrs I spend prepping that ammo, targets, and range gear each week; each trip begins to look like a pretty significant investment. If Brux, for whatever reason, doesn't offer to help you out; I would seriously consider biting the bullet and having a new barrel made.

Sometimes it’s not the barrel.

 

[Ccrider]

just cleaned before the pic. soaked overnight with wipeout, cleaned tht out and then soaked with C4. i use

If those photos are of a cleaned barrel, I would adjust my cleaning process. I see copper and carbon in the barrel. It is far from clean. I have barrels with a lots more marks and cracks than that that still shoot.
It may be helpful to show what the throat looks like also.

 

[swadiver]

i am going to clean it with JB Borepaste and then shoot it this weekend. we will see.

meanwhile, i wish it would shoot even close to this 13.5 twist Krieger 6BR barrel on a blueprinted Remington 700 action. this one has always been a shooter. it turns out 70 Sierra Matchkings are an awesome bullet in a bunch of 6BRs i have tried them in. this is with N135. 5 shots @ 100.

 

[Terry]

Have you called Brux? I’m sure they’d help you out.

This should always be the first step!

 

[Eric Leonard]

try some 8208 with the 80s and lt32 with the 70s

 

[swadiver]

i have used 8208 with 80's but i got more consistent results with N135. I have LT-32, but never been able to get it to work in my 6BR's. it does awesome in a 14 twist .223 i have with 52 gr bullets, but not in my br's. N135 has proven to be more consistent for me. the target pic above is 70 smk's with N135

LT-32 is a well known performer in the 6PPC as well, but i have had much better results with N133 in my 6PPC. maybe the florida humidity has something to do with it.

your probably right but, i am hard headed and i like a challenge. i am going to still see if i can get it to shoot. if not, i will replace it at some point.

I am not seeing the caliber mentioned in the conversation thus far. It may be that your 12 twist barrel is too slow for those heavy bullets. If it is .224, I would not shoot more than a 55 grain bullet through it and expect accuracy. Even then, not all 55 grain bullets will stabilize properly, but that is my rule of thumb. It has to do with the length of the bearing surfaces. If it is 6 mm or something in that neighborhood, others may be able to address the proper twist rate for that bullet. Yes, your barrel is rough. My gosh! You oughta see my current lot of Savages with stock barrels though. My borescope scared me into replacing several until I realized the ones I am throwing away shot extremely well. They just require an inordinate amount of cleaning afterward. Try lighter bullets in your 12 twist and see if you don't throw some tighter groups.

In the OP right under the pics it states 6BR.

Run a set of Tubb fire-lapping/throat maintenance bullets over it, then scope it again. Or get someone to diamond-lap it.

 

[swadiver]

what's the record for a 5 shot group shot a 100 yards?

I bet that goes over like a turd in a punchbowl.
