I'm just finished rebarreling one of those 'not so great' Rugers. This was an older tang safety 7mm Mag, wood stock, blued metal. I first had it in the shop with reports of 3.25-4" groups, so I took a look over it. I didn't see anything seriously wrong with it, a little binding in the mag box with the bottom metal, a good bedding job, aftermarket recoil pad, tuned trigger. So after fixing what little I saw, I re-assembled and took it to the range. Still showed 2-3" groups. I was going to take the barrel off and re-lap in case there were problems there, and when I had the barrel in the vise, and the action wrench on it, I slapped the action wrench handle with my hand (quite softly I might add) and the action popped loose. I thought 'BINGO'. After torqueing the barrel on tight (not super, slam it with a hammer tight, just tight) the barrel indexed over 1/8" further so the stock line was now in the middle of the caliber markings. That didn't work either as it still shot poorly. The barrel tenon was machined very undersize also as it wobbled side to side looser then ANY barrel I've removed.
So long story short, I ended up with that rifle back as the owner just couldn't bring himself to pawn it off on some other fellow and decided he'd like a new barrel. When I took it back apart, I ran a piloted .010" tap through the action and set it up to face the receiver. The receiver face was WAY out of square with the threads/bolt bore. It took over .005" to clean up. It now has a stainless shilen on it, and I have yet to get to the range to see how it all shakes out. Hopefully it will be a rifle he won't want to get rid of after all this.
