I sent them a factory 700 stainless barreled action about 10 years ago, and had them true it up and rebarrel/chamber it. I had them do a tight neck(.333) 300 weatherby, for a 1000 yard BR gun, and paid extra for express service, I also had them install a brake I already had, and blend the barrel /brake contour. They did as I asked, and I never had any problems, Workmanship was great, it shot as well as my other 1000 yard rifles, cleaned up easy, and the turn around time was as promised.
I' have a Winchester push feed they "trued" and put a barrel on chambered in 30-06 Ackley that shoots aws well and a Rem 700 in same caliber i had built by Darrle Holand with a Hart barrel , so I'd say that they did somthing right.
Now that said I did get a bad barrel from them one time but it was replaced with no problems at all.
I live in Brookings, OR, where PAC-NOR's based. I am not affiliated w/ them in any way. That being said the Pac-Nor barrels chambered and installed by Gunner's Sport Shop,(also in Brookings), are legendary around here. Gunner's is more famous for thumbhole stocked hunting or varmint guns but is getting "tactical" with the help of some friends.
Bought my first Pac-Nor Barrel in 2005 for my 40Xaction chambered in 22-250 (1x12 twist and 5 groves). They trued the action, chambered and installed the barrel. Great shooter. In 2007, I re,placed that 22-250 barrel with a 3 grove 1x12 SS and also had a 6mm Rem 3 grove 1x10 built on a 700SA. The original barrel has been set back and is still killing prairie dogs on a 722 action.
The two three grove barrls (22-250/1200 rds and 6mm Rem/800 rds) are absolutely wonderful. The shoot bugholes and don't erode easily. Both have been easy to clean.
Call Penny and buy one. You will not be unhappy. Old Doug in GA
No you can order a remington barrel with a savage style barrel nut, makes an easy switch barrel system.
I have a half dozen barrels and they did all of the installs. I had one model 7 with a #2 contour that did not shoot as well as I wanted. They took it back and dropped in a new barrel with no questions asked. New barrel was 1/2 to 3/4moa which is as good as I have ever seen for something that slim.
