Mine is also an AIII like browningguy's except in 270. I bought it used at a good price - good price because it wouldn't shoot under 4" at 100 yds. Since the barrel was making 100% contact with the stock, I bought a semi-finished stock from Richard's, and pillar and glass bedded the action, free floated and bedded the barrel channel, and it still wouldn't shoot under 3". I marked the lugs, and only one lug - and on only one spot - was bearing on the receiver. Broke out the Go, No-go gauges, and the Go gauge wouldn't even chamber. I was able to lap both lugs to get about 80% contact without the No-go gauge being able to chamber. I recrowned the barrel, and headed to the range. Finally, groups under 3/4". Granted this rifle should have never left the factory as it did, but I probably couldn't have purchased it at such a cheap price if it shot well.
