New Barrel...Bad Barrel...Borescope

[1952]

I bought a new barrel and before I shot it I put my borescope through it and found an improper cut leade. The lands stood up so far that my borescope would catch on them. If you look left of the mirror you can see the lands just faced off sticking way up. I wonder what accuracy would have been like?

That is strange. It’s like the lead angle on the reamer ended larger than the bore diameter.

There definitely should not be a step there.

 

[1952]

That's what I thought. Wrong reamer.

Dull reamer. You can see metal coming off the trailing edge of the leade. I've seen this many many times over the years.

I believe the reamer might have been damaged. I remember cutting that chamber and I had several issues. All of which I thought I resolved after recutting the chamber completely. Since the barrel was cut short, redoing the chamber was not a problem. I did not see that weird leade end. Yup. That's weird. No doubt, if you had sent me the picture instead of posting it here, I would have agreed with your assessment. But you didn't.

I already told you I would pay to return it and refund your money. And was sending a shipping label tomorrow.

Btw: I have always hated the reamer.

I see it!

Looks like you’re being taken care of.
It’s the service before and after something is bought that sets business apart.
Urbanrifleman sets a great example of how things should be done. Way to man up.

There was something different about the blank. Completely unusual. The bore diameter was slightly smaller than the couple hundred other 22-7 blanks I've pulled off the shelf. The bushing was sticking.

I went to a slightly smaller bushing and everything seemed to be fine. I just figured it was fine. When I borescoped I did not see that step. Which I never looked for it, so I did not see it. Although, now it seems obvious. Maybe my lens was wet.

I think maybe the tip of the reamer got damaged somewhere in all the confusion. Like I said, I have always hated that 22 Creedmoor reamer.

Been there. Some people would rather complain than seek help or restitution....no matter what you say or do.

What the hell. The man ask a question. He never mentioned anyone by name. Never complained about the follow up service.
Kudos to Urbanrifleman for sticking his neck out and explaining what happened.

Sounds to me like nothing more than a good learning experience.

And the winner is? The shipping company.

Since we got all that figured out…one thing is for certain, urbanman is passionate and proud of what he does…that went down as I suspected it would had we known it was his.

So I’d like to highjack and learn something…how would y’all fix it? My thoughts would be to use a throater and that would easily clean it up without adding any significant freebore.

Second, whose barrel is that? The lands are near perfect, I’ve seen more U shapes and trailing edges lately than I’d prefer to get. Saying that…one of the better barrels I’ve ever had was a U shape and everything is still shooting great, I just like to see those crisp 90 degree lands at the end of the freebore.

 

[1952]

Damn urbanrifleman, I didn't want you to out yourself. I wasn't going to.

I just wanted to show what I found and why it is a good thing to inspect before shooting.

Yes, you were very good about making it right and I really appreciate it.

This illustrates the area of the reamer that dulls the soonest. Obviously a new reamer is forthcoming. I would go in with a new reamer a short ways and take a look. Everything should clean up. If it has, adjust tenon dimensions.

I'll start a new thread sometime this week with pictures of reamers and barrels.

I think it's possible I hurt the reamer.

Honestly,I never have problems with a blank being different. It simply never happens.

Maybe that reamer just decided to finally take a dump. It was never a good one. I admit I've cut LOTS of chambers with it. Slow to cut, but always finished well.

This is the only reamer I own that I could heard it squeak when it cut.

These reamers that have a big shoulder and a tiny bore take a lot of abuse. Even with pre drilling.

It was never a good one.

PTG?
