Reamer regrind

I have a 284W reamer with .315" neck, could PTG regrind this reamer to 6.5x284 with 291 neck or better to go with a new reamer with my specs. thanks

They could, But I wouldn't send anything to them that you aren't willing to lose. Many people have sent things to them and never got them back. It would also take about a year to get it back if you did get it back. And it could be messed up.
They were a great company till about 5 or 6 years ago, Something has happened there. Look at their google reviews. I have had several problems with them to the point I just don't deal with them anymore.
Talk to Manson or JGS about what you need.

I would more recommend Manson
Might take a month though, but results are likely to be more on point and have all flutes cutting which is most important in a chamber reamer since it is the front that actually cuts.
Last I used them I think each operation was approx $60 (Plus shipping)
Each dimensional cut is a different operation / so a different setup
----------------------
I also was going to have a Custom Reamer made from them in Oct but the wait was 5 months.
I wanted a specific thoat length.
Instead I ground the throat of my reamer down myself and then bought a throating reamer from them
----------------------
It is a shorter wait time to, buy an instock reamer from them, then have the dimensions reground to the specs you want
Keep in mind again, each alteration is adding $60 to the price of the reamer
So if you make 5 alterations then it is cheaper to just have a custom reamer made
But thats if you can wait 5 months for a full reamer.
An in stock Altered reamer may only take a month.

A while back I called JGS about having my .22/243 reamer sharpened. Month and a half+ and $140. Remember when you could buy a new reamer with a removable pilot for that much?
Yeah, Manson quoted me $270 and 5 months,
and couldnt hold .0005" tolerance without charging $50 extra on top of that
If I want a certain Dia. neck, then I want a certain Dia. Neck ... What the heck?
I thought someone like Manson could do it no sweat, it makes me wonder what we're really getting if we have to request it ....and they have to charge extra to hold good tolerances that I would think should be held to begin with.
(I mean I can hold .0005" with a manual lathe??? - When I was a CNC machinist we usually held +/- .0003"
in the morning anyway, before the bearings warmed up, then we relaxed it to .0004")

It's like, "Oh ooh wait! You want a good reamer? Oh ok well we have to charge extra for THAT!")
--------------------
they must have not wanted repeat business, or I don't give them enough repeat business
one or the other. But at least they said they could do it which i think is better than PTG.
I still prefer Manson regardless because their Reamers cut like hot knives through butter.
Effortlessly with no chatter,
---------------------------------------------------------
Copy and pasted email response:
Good morning John,
We can make the reamer to your specifications. We do apply additional charges for the tighter tolerance requirements.
The reamer cost will be $270 for the reamer plus an additional $105 for the special tolerances.
If you can live with -.0000 / +.0005, we can cut the additional cost to $50
We are currently quoting five months for production.

Let me know if you have any questions and if you would like to proceed.

Best regards,
Ray

A man of your talents should be making reamers for us.
 
I used to get heat a bunch of years ago for not using pilots on 4 or 6 grooves. I dont because theres no need. But on a 5 groove with a 6 flute reamer there will be tool push off. Period. Some reamers and barrels it will be minor and you can get away with out a pilot. Some will fight you to the end. You can ream the rifling out so the reamer doesnt cut it until the very end, theres plenty of tricks you can can play. But on a 5r a pilot helps. It doesnt have to be tight. About half the barrels I do are 5r and I chamber barrels 5-6 days a week. Its not chatter, its push off. I can see it in a groove immediately. The longer the reamer and the longer the freebore the worse it will be. Reamers flex a lot. You have to support the front of the reamer on some of these. Not all reamers will require it. There are no rules here.
 
I'm with you and do the same thing. I'll do a little extra pre-boring on 5R's and use a pilot. Everything else I leave it off - it makes the flush work a lot better.

Ever thought of getting 5 flute reamers in the common chamberings?
