YOU will reap what you sow.

That's uncalled for.

My question is how’s it shoot?
Would be interesting what it does.

 

[urbanrifleman]

PTG?

Nope.

 

[Judd]

I bet it would shoot, it’s cut straight.

Might rip off the jacket. Don't know.

It's funny. I borescoped the chamber as I do every one. But I didn't see this, which seems glaring at this point.

Just proves I that 100% first time quality is still unobtainable. No matter how good intentioned one is. Though we strive for perfection, Deming new that perfection was an idea only. And as sheer volume increases over time, opportunity for failure, even in the same small percentage, increases.

If I shot 22 Creedmoor I'd shoot it. Just to see.

I do know a guy with a Kauger that could shoot it. Although it is a 7 twist, which will be overspun at pretty much any 22 Creedmoor load, and I don't recommend lots of overspinning of bullets for shooting small groups.

. Even with pre drilling

Yep.
The leade of the reamer must be razor sharp to cut cleanly at the end and is also is required to cut from start to finish- which is minimized to the extent possible by pre-boring. If i were doing dozens of barrels in any given chambering I'd be using a rougher first to save the wear and tear on the finisher.

I've had great reamer life pre boring.

I think this one was a lemon from day one. I'll have to do some more research.

Just as a reference, I use caliber specific core drills 98% of the time with a flush oil system. The throat area of the reamer is cutting .500"+ of the barrel. I get about 60 chambers before I have visible wear in the leade. That's when I take them out of service. How a reamer is lubricated and used can shorten the lifespan.

Core drills are my favorite

I agree. It would be an interesting experiment to shoot it and see how it does.

 

[Rewinder]

There are some gunsmiths that will not stick one of their reamers in a used barrel.

I would guess it would be pretty hard on bullet jackets. Probably copper up would be my guess but you never know

Your statement is BS! The OP never bad mouthed anyone... never mentioned the smith... never said anything negative about his experience with the person who chambered it... never said it wasn't being handled by the smith.... he just showed a photo and gave his experience. He just showing that things can happen.

Look at barrels enough and you'll see things like this quite a bit.

One time....... right.

i would like to shoot it and scope it every round to see if that would break or wear off. i would prob go max of 20 rounds.( not that i dont have anything else to do.
