The most accurate sporting weight rifle I've ever owned was a M77 in 338. With one particular handload, it routinely shot one hole 3 shot groups. It never shot worse than 11/2" groups with any of the different bullets I tried, and most shot less than an inch. The rifle had been glass bedded. I also still own a M77V in 22-250. No factory loads have ever shot more than an inch, and I have shot a number of one hole 3 shot groups. I also had a M77 in 30-06--with good handloads, it too shot sub moa groups regularly. My sense after working up loads with these guns is that they were easier than most rifles to dial in. I also love the built in bases. If your limited to factory loads, go by 5 or 6 different loads in the weight you want--I'm sure you will find one that shoots great!
