Re: How do you feel about Pac-Nor
Pac Nor has done a great job with the rifles that I have sent to them in as far as chambering and trueing the action. Pac Nor also has a revolutionary type of rifling system that is far advanced over most barrel makers, a best friend of mine invented the buttons for them. They also have a system of measuring the uniformity of the twist rate that is in the barrel. If/when the button skips or digs in when it is cutting the rifling, the vibrations will be changed due to the twist rate change. Pac Nor and Anchutz are the only companies that have a system like this, they can actually plot the twist rate of a barrel every 0.200 of an inch. Pac Nor uses a very special kind of steel unlike Hart, Douglas, and Lilja and others. The Steel that Pac Nor uses is tough.
Having said all of the above, I have never had a bad Hart or Lilja barrel, and I have had a bunch of Harts for sure.
One thing that I have noticed is that the three groove barrel seems to produce about 100 more feet per second over a 6 groove barrel. I seem to be able to shoot hotter loads in the 3 groove barrels, and I can only guess that the engraving pressure on the bullet is less in the 3 groove, but that is only a WAG at best.
Pac Nor has about 2000 reamers on hand. If you send them a round seated at a particular length, they will throat the barrel for that length of seating depth at no extra charge.
If you have a particular long range rifle that you are wanting, it is good to deal with a particular gunsmith that specializes in that type of thing, it is worth gold in the long run.
There should be no doubt that Kirby (50 Driver) on this board should be one of your more trusted gunsmiths both in his knowledge of a long range cartridges and his machinist abilities.
