Has anyone seen this?

Let's hear some thoughts on this..........

He flunked Machine Shop 101 when dealing with the problem of establishing a third point dead true with points in a piece that is not straight with it’s self.

Basic machine shop practice dictates that when dealing with a piece that is not straight, you must employ a method of machining a third point true with two other trued points, the most affective way to accomplish that is by. single point machining.

I chamber barrels to were the actual lead and throat are within .0002 inch of the chamber. And yes, I Know how to check it to insure that type of chambering accuracy.

Another thing. The ID of barrels is not curved as he stated. The ID wonders from one direction to the other through the length of the barrel.

If you know what you are doing, I categorize this as a solution to a problem that does not exist.

I do see one benefit. You could maintain the same chamber from barrel to barrel if you have trouble keeping your chambers consistent from one barrel to the next.

Jackie you are right. This just adds another problem that aint there to start with.

[Butch Lambert]

That is a crock! You couldn't machine a bow in a barrel if you tried. Drill, bore, and ream will make a good chamber and throat.

[Jerry H]

Well maybe he has a really crooked lathe alignment. I haven't seen throat misalignment's near that bad that he is talking about. 2-3 thousandths would be pretty bad in my opinion. The chamber throat junction he is advocating would more likely be way worse than a properly done traditionally reamed chamber.

The ACE is a neat way of chambering a barrel but does not hold true to first indicating the bore square then drilling boring then reaming. Indicate drill bore ream, the reamer now only follows the throat of the finished chamber which is indicated square to the bore.
But still the ace system is pretty neat.
I can see the ACE system can work that's for sure but you would have to have a very accurate double setup and still have more runout then, indicate drill bore ream in one set up.

Explains why I can't shoot straight, thanks to these folks, I'm finding out that it's the first inch of a barrel that is the most accurate. All along I have been cutting off the first 3 or so inches before I even start a chamber...

I believe he is telling you the first inch or so of the breech is where the lap of a new barrel stops and changes direction. It is not the same size and shape as the rest of the bore.

After reading JamieD posts
I have to take my hat off to him and want to thank him for taking the time to post. Today CNC machines can and do things that is next to impossible on a manual machine, repeatability in accuracy for one it's all about the numbers. I heard a looong time ago that there is more than one way to skin a cat.

I´m quite sure Andy from Bix n´Andy showed a very similar concept at the Austria WBC in 2007, not sure if it ever passed the prototype stage. I remember Jim Kelbly saying it could be difficult with the "chamber bit" being deemed as a very short barrel in the states, thus causing some kind of regulation issues, not sure in what way. Been a few years so the memories are a bit vague!

Jamie,
I appreciate your innovation and especially the way you handle people slamming your product while being totally ignorant to it. Best of luck and hope it works out.

Mram10,
Do you have the slightest clue or do you just watch You Tuber Vid's to increase your IQ?


TactiKool & Remage Nut jobs will be all over this.BS.


I personally wouldn't waste my time or monies.

[Gappmast]

Jackie is right. When a barrel is drilled the drill is going to be pushed around by any harder spots it finds.

[Rubicon Prec.]

I am guessing the barrel/throat portion still needs to be set up in the lathe the same way(s) every precision rifle builder is doing now, to make sure the throat is parallel and concentric to this big ol’ banana shaped bore?

If I found a chamber I cut was .003”+ of eccentric to the bore just ahead of the throat, I’d quit.

I personally see it as a solution to a problem that doesn’t exist, but being the capitalist I am, I hope they make millions.
