Chad, you may be right, but ... the thread crush allows ~~ x degrees or discretion if the torque can vary from 25 foot pounds to 250 foot pounds. ............and I have shot some great groups with finger tight barrels in a Mauser with inner lock ring.
I have ordered two custom "no neck turn reamers"
1) 6mmBR 0.272" neck from PTG
2) 223 Rem 0.250" neck from Manson
They both had some throating adjustments that cost extra.
They both took many moons to arrive.
I have the plumb bob on the end of my 50 foot deck and a benchrest set up.
But a lot of scopes do not focus at 50 feet.
So I have figured out which telephone pole features are plumb, 200 yards out.
The worst problem is some scope levels move when tightened.
I have a couple rifles to build...
Any barrel will shoot until it fouls.
The Shilen select match barrels like mirror inside. They have been hand lapped.
Just like looking into my Lilja, Krieger, Benchmark, Hart, Parker Hale, Walther Lothar, Bartlien, ect
I have screwed in enough rem 700 take off barrels to think that the threads are clocked. The sights are either on top or on the bottom.
I do not have that ability in my shop when I single point cut threads on a manual lathe.
I have reloading dies and guns for 63 cartridges.
The past few years I have concentrated on 6.5-06, 280AI, and 7mmRM..
Outside of my concentration in 2020 I will shoot a factory 243 Sako , build a 7mmSTW on a Defiant action.
I will probably put (2) deer in the freezer.
I just checked what I have been hunting with for 2 years.
WW 30-06 brass for 6.5-06
Nos 280AI
WW 7mmRM
Nos 7mmSTW
No trouble with loose primer pockets, and I am no stranger to a work up to loose primer pockets.
I work up until I see an increase in extractor groove anywhere around the groove...
I have built a number of Rem700s and pre 64 Win M70s.
I have only built (4) Savage bolt actions; 223, 250Sav, 280AI, and 300WM.
In all 4 cases I cut a shoulder on the barrel and did not use a barrel nut.
The 223 and 250S shot better than I can. The other two not so much.
There are problems with...
Have built a couple... but have not been ground squirel hunting lately, so I have not been shooting them.
Bolt actions are fine.
I did build a 17M2 on a 10/22 that blew up in my face
I have spoken with the CEO of a knife manufacturor when he jogs by. So I switched to his brand. I am so honored the young buisnessman would speak to a creepy old man like me.
My reamer From Pacific Tool and gauge I got a 6mmBR reamer with .272" neck and throated for a 87 gr Vmax.
I have never had to turn a neck of Lapua or Rem brass. The accuracy is amazing
I have always had good results with PTG, but I am nobody. I build maybe 3 rifles a year for myself with PTG parts.
Longrifles posting above is a massive operation with high standards. Whatever he says counts for more.
The girls that answer the phone at PTG know nothing and Dave Manson may be...
An 18x40 is not going to be easy to move.
If it runs it is definitely worth $500 even if it never gets the right tailstock.
I have not modified tailstocks but I have made a steady rest for a 12x36 Clausing.
If you are old, worn out, and rich, forget it. If you are young, energetic, and low...
This is a 6.5-06 I built on an old Rem 700 action with a Bartlein barrel.
This is a 280AI I built on a pre 64 Win M70 action with a Bartlein barrel
I build so many rifles, I can't remember them unless I put tags on them.
I work up until the extractor groove shows any growth and back off 3% for temperature stable powders. In 1956 when Vernon Speer was explaining how to write a load book, he said back off 6%. That was for a load book and stable powder was not available then. The derating on 6mmBR must be done on...
I have rechambered a number Tokarev barrels on a mini lathe from 9x19mm to 9x23mm.
Mostly I used it for 18 years to spin an arbor with a wife wheel. I have now given it to someone who is rebuilding it with sealed spindle bearings, a new spindle, metal shift gears, a new belt, a new belt shim...
