Same reamer for chamber and dies?

[L.Sherm]

I haven’t had the bad luck with ptg like others have and Kiff has made some very nice reamers for me and alway helpful on the phone.

I wished I could say that, I recently purchased a 20 Prac reamer that is way under at the back end. It wasn't directly purchased from PTG but a factory 223 piece of brass won't even chamber after necking it down.
This is the second PTG one that I've got im done forever I was hesitant on this one but was suppose to have 1 chamber cut with it, well if that was the case it should have worked BUT.

I'm not doubting anything really but will just say that it takes a lot of diametrical difference of a tapered case to keep a round from chambering. How did you verify reamer diameter to be small, besides how it chambers? Honestly, there are a lot of areas that are more likely to feel and be problematic in that regard. Not defending PTG either but will say that their quality has not been their MAIN issue, but service. Yes, there are exceptions to that also but I don't see the need in everyone jumping in and giving their examples to prove that, either. I'm only interested in YOUR issue.

I measured a factory case at the .200 line.
I took the barrel off the action and with the factory case in the barrel its a little snug.
Factory case is about .3738 best I can measure. I guess I shouldn't say it won't chamber not freely doing the Wheeler method. A sized case .3750 has .130 protrusion out the back of the barrel and won't chamber not even close.
The first PTG reamer i had this way 6-7 years ago I sent to JGS and called back and told me it was .002 to small at the back and this one appears to be about the same.
I have another 20 Prac that my brass I size with my Redding FL 223 bushing die chambers just fine, ironically it was chambered with a PTG 4-D reamer

 

[L.Sherm]

And no there isn't any burr in there I looked with my borescope. Chamber neck is .233 and I sized tge neck to .227.
I've already ordered a 20 Prac JGS reamer .

 

[L.Sherm]

Theres about .025 difference in the protrusion from a sized case to new one, .004 difference in the datum line length using a comparator.

Fair enough. My point I guess as much as anything is that you said "it won't close." There's a long way between the wheeler method and "won't close" due to case taper etc. I can believe what you said better now but does it crerate a problem either chambering or extracting in any way? If so, I'd fix it but if the only test it fails is the wheeler test...forget about it. As far as I know, that method is intended to find the "just barely touch point" of a bullet.

 

[L.Sherm]

It won't even chamber a sized case, the handle will close about .25".
I'm gonna fix it when the JGS reamer gets here, I speced every thing the same and the .200 .3.769 probably what my current 20 prac is best I can measure from fired brass, taking into some spring back.

If it creates a problem, either a smaller die or a bigger chamber but if we're talking wheeler method of barely detecting feel, rock on.

 

[L.Sherm]

I've tried 2 different dies, im not even trying the small base die thing if a FL die won't take care of it im not interested.

Ok. We're getting somewhere now. I strongly doubt your problem is diameter based on that statement but everybody has a different definition these days of certain things, like won't close. If it solidly stops before closing, I don't think it's a diameter issue, or at least not very likely. This might be one of those things that are plain as day in my hand but tough to tell on the internet.

All the more reason to doubt the problem is diametrical.

One case would answer this.

 

[gunsandgunsmithing]

I'm happy to help but I get the feeling your mind is already made up and you may well be right. Let us know how it goes.

 

[L.Sherm]

Listen i can't even force the bolt to close on a sized case maybe with a hammer.
The print i got with the reamer says its suppose to be .3769 at the back so its obviously not even close.

 

[L.Sherm]

The same piece of sized brass chambers just fine in my other 20 Prac no resistance at all.

Could you make a sizing die with a chambering reamer by cooling the reamer in a refridgerator and warming the die blank? The reamer has shrunk a bit and the die blank has expanded a bit and once they die is back to room temp and smaller, maybe it might work.

No

A sized case .3750 has .130 protrusion out the back of the barrel and won't chamber not even close.

I just had a 6.5 CM pre-fit chambered and that is what I measured before I installed it and set the headspace.
