PTG UNI Throater

Ordered a 6.5 Uni Throater bout a month or so ago delivered in 4 days, cuts great my hat is off the the people at PTG they do great work.

The emphasis should be on "cuts great". When you use one of these throaters, realize that what you're cutting is mostly lands and it doesn't take much effort to go WAY too far. And there ain't no puttin' it back either.

If, like me, you're not a real gun smith but you like to play one in your garage, remember that the rule with these things is "measure three times.... cut half of what you think you should.... then measure three times again." The effort required to turn a throater is nearly nothing, so be careful and check, double check, and triple check.
 
your exactly right I think I cut about .020 at a time, take out reamer flush in napatha, oil,adjust go back in cut 20 repeat, first I done a J&B treatment to get most of the carbon out, then flushed and patched that out, then oiled the barrel oiled the reamer and went to cuttin, still need to go a tad more but if it shoots ok will leave it be. My hats off to the garage gunsmiths or shadetree gunsmiths lol

Got THAT right!

I had a wildcat barrel chambered last year by a Very Well Known Gunsmith. Supplied reamer was intentionally designed, ordered and received with 0.000" throat as I'd also ordered a throating reamer. As this was a wildcat and I'd intended to use a bullet requiring rather longish throat to make best use of case capacity, I wanted to set that throat dimension myself once I got the barrel back for mounting.

VWKG advised against this, indicating he couldn't guarantee accuracy owing to his not being involved for this final step.

With which I was entirely comfortable.

Understand that I respect those with expensive and heavy metalworking machinery and the knowledge and experience needed to get the most out of same! As I lack the former I have to rely on my own skills once in awhile to accomplish something I want to achieve. Such was the case with throating this chamber.

Which went very well actually, done entirely by hand... slowly... with provisions to keep that throater both axially-centered with the bore as well as controlled for cutting depth.

Throat was cut in three steps, checking depth each time as well as making a chamber cast until it was where I thought I'd best leave it, within 0.005" of where I'd targeted it to be in consultations with the cartridge's designer.

Quite unexpectedly this chamber allowed me to tie an existing NRA National Record at 1,000 yards (Senior, Open Sights, 20 rounds for score) late June of '16: 200-15X, on it's very first string in competition.

So yes, "shade tree-ing" has it's merits... as long as one is prepared to accept the responsibilities for one's activities.

    how did you keep the reamer centered in the bore, I mean I think myjob maybe a little off, from the borescope it looks to be cut a bit more on one side, but it may shoot the best I will be working on some shooting today if it shoots good so be it I think

should be red....now the fight starts!! lol
 
Bahabahaahaha you drive them red tractors, I use to drive a 1066 all the and a 1468 with the V8 love that torque
that 1468 is kinda rare, the new red and blues dont compare to the old IH's. they truly dont make em like they used to. neighbor has green, I got blue--we pass each other going to dealer shop constantly for repairs, we like to give each other a hard time about it. lol

that was a long time ago, I remember going past the IH plant in Louisville Ky on the way to NFMS and seeing IH tractors outside
 
I throat all my 308 chambers with one. I've only ever messed up once. Trying to do the job with too many distractions (Kids, wife, work, phone all at the same time).

My smith had to take 2 threads off and re-headspace it for me.
