I barreled a SA a customer supplied. NOT impressed! (not impressed with their reamers, either!) The action arrived with NO specs supplied for barrel thread diameter. I measured in 3 different places and got 3 different measurements. I decided to call PT&G and ask. The answer I got wasn't a 'good' one. I was told it has an 1 1/16-16tpi thread. Previous experience with PT&G told me not to disagree or ask for someone more knowledgable. That threaded hole was definately NOT 1 1/16" as I have many Remington barrels in the scrap "pile" and I tried several. They all fit sloppily. I know how to measue, too,,,,, been using precision measuing tools since 1973. The threads had been enlarged, but by how much? My solution was to turn a "stub" of CR over sized and thread it 'till it fit the action the way I wanted it to. This took an extra 45 minutes of my time. I 'charged' for that time. The thread ended up being enlarged by .010" to 1 .072". This info should have been supplied with the action if they (PT&G) are going to supply "trued" actions. To top it off, their "trued" threads showed evidence of being "trued" with their OS tap (and I was informed by another gunsmith who has a business arranement with PT&G that they use a piloted tap). Piloted or not, most accuracy minded gunsmiths single point barrel tenon threads. These "piloted truing tools" are hobbiest tools , IMO.This customer does all the work, besides barrel fitting and chambering, himself. I've not heard back with an accuracy report, yet. But I will, when he has time to complete his build and break it in. With the lack of info provided with the action, the poor customer service I get over the phone and the fact they used a piloted tap instead of single point threading barrel tenon threads, I wouldn't buy one. I buy their bolts. I've had no problems with them yet, and they seem to be they only source. I've used their Oberndorf bottom metal when I needed something not obtainable elsewhere. They're kinda' like shopping at Walmart. Ya' get what ya' pay for! Tools and supplies for the masses, not for the 'particular'. Shop wherever you want to.
