Sometimes I think it's better not to look. Like the sausage being made.

But I got one of those cheap Lyman digital bore scopes recently and it's too late for me, I already been mooned...

Wanna see ugly?

Ain't that a peach...

My 12 twist .22-250AI. Which has kinda fallen down on it's face lately. Wonder why? How in the hell I let it get THAT BAD, I'm still not sure how it actually happened or why. But it did.

Took a shit ton of effort, but did get it clean again. JB is the stuff.

Still kinda like looking at the sausage being made though [Big Grin] .

Thankfully, none of my other barrels held any nasty surprises like that. Not that they all look awesome, the 6-284 is earning it's rep for burning throats. But it's clean all the way through (same cleaning practices as the ugly one above?). Can't scope the .17's though, .20 is the smallest it will fit in. Think I'm gonna JB the shit out of the .17's just on GP, since I can't really look and all, ha-ha!

You still using that wipeout stuff? I’m not too impressed, personally. I mostly use Butch’s with a little Kroil.

It sure looks ugly all magnified. I think a lot of barrels get trashed when some real TLC would revitalize them.

So what happened, groups open up, pressure up? Hows it shooting now?

Geordie, groups opened up. And it started copper fouling like a SOB.

Started missing some head shots on 'chucks that shouldn't have been misses. Bench tested, groups had opened up from 3s and 4s to 7's and 8's.

1,800 rounds on it. Too early to go that far south.

And yup, still using Wipeout. Still going to keep using it. All the others are fine, including fire breathers like the 6-284, .20-250 and .20 Dasher. Something went haywire with this one though.

As we all know, when you magnify anything by XXX% even a sheet of glass looks pretty gnarly.

Dave, did you do the colloidal graphite 'break in' treatment on that barrel?
Do you think that molycoatung boolits might help in tempering that throat damage, by allowing a layer of protection and lubrication that decreases bullet engraving pressure?

I went nekkid bullets (and WipeOut) on my Redline barrel, and a few barrels, prior. Sure is easy to clean, but I'm kinda skeered to even look down the tube for fear of finding the alligator has surfaced!

Fred, that one did not get the colloidal graphite break in, all the others mentioned though, did.

I do not think moly would have made any difference in the condition of the throat. Ran moly in the last barrel on this rifle, it died right on schedule within about 100 rounds of when the barrel before it which had run naked died. Moly can have some benefit, depending on application, buy my opinion, this ain't one of them.

That said... This barrel has head a steady diet of WS2. Long story and I won't bother with it... But I didn't go that route with any thought of longer life, and it doesn't appear that it's going to offer any. It's one of the differences about this one compared to others which have no hard carbon fouling in them though. But, I can't begin to say if it was actually a factor and if forced to hazard a guess I would guess not.

Here is the throat of my 6-284 with only about 250 rounds on it, over 200 of those at coyotes, never shot a long string or got very hot.

 -

Any my .223 AR, less than a year old, over a thousand rounds on it, lots of rapid fire, longish strings. In the process of being cleaned.

 -

Gas port, after cleaning.

 -

No hand lapping here [Big Grin] .

 -

RRA, which I'm pretty sure is a Wilson. Hasn't ever copper fouled much, always cleaned up fairly easy, shoots pretty good for a machine gun I think. And does actually look way better than many other factory barrels I have looked at.

BTW, that 6-284, being a 13T, I had it throated with zero freebore - which you can actually see, and awful damn glad I did!

As reading this report, I had a sudden recollection. Didn't DAA at one time either advise against, or at least "cautioned" using a borescope?

Everybody can be curious, from time to time, but even as shoes wear out, it's a little discouraging to actually see what high performance can do to a barrel. All you have to do is look at that 223AI photo versus the 6-284, freebore withstanding.

That's the thing about the relationship and the differences in tame chamberings, such as a 308, and how long the accuracy holds up. I have a 308 that I have treated like a stepchild for years, but it keeps plugging along while the barrel burners keep stacking up behind the door.

Now, being economical and frugal (occasionally) what is the consensus about solutions? Also in all those photos; are they taken at a standard depth? I'm wondering about cutting an inch and rechambering, versus the loss of a bit of performance. For those of us where money is no object, I suppose it's kind of fuck that! So, where do we go from here? I'm a little, the shine is off the rose, and being a slave to either/both performance/accuracy.

Maybe that answers my question about the sudden popularity of the Creedmoor stuff? I don't know? Is it a compromise type of phenomena? Neither fish nor fowl?

Good hunting. el bee

Only issues with chopping and rechambering are shank for shoulder and bore diameter. If you can reach normal nominal bore diameter and still have enough shank for threading and shoulder, it can be a good way to extend the life and save some money. That gator hide and erosion enlarges bore diameter though. Sometimes you have to go just too far in to get back into good barrel, doesn't leave enough O.D. for threading.

I ordered the barrel for my .243AI with an extra 6" of straight shank on the back to allow for multiple setbacks if I choose.

Have an 8 twist .22-250AI in the corner that goes poof with 75's and 80's but has enough shank and the bore looks good enough 3" in that I'm seriously considering having it setback and rechambered. Thinking .22BR for it this time though. Whether I do or not really depends on how much I can get it done for. My regular guy, no way, just wouldn't be worth it on a used barrel. Not everybody has a reamer I'm going to want to live with either.
