I only have two bolt guns, but both are pretty dang accurate. One is a 1984 vintage Ruger M77 with the heavy 24" barrel chambered in 308. I picked a good multi-purpose bullet and powder and tinkered with the load until I got it where I wanted it. That gun is my main hunting rifle, so it sports an older Nikon Prostaff 3-9x40. The loads I shoot are a 165 Sierra Gameking over 43 grains of 4064 in Hornady cases. I have had 5 shot groups of .77", but 1" is the norm. It just so happens that those loads are EXACTLY calibrated for my BDC reticle. Making a cold bore shot at 350 yards on an 8" steel target makes me smile.
The other would be my CZ452 Trainer. When I had the scope on it, it would shoot Federal bulk into 1.5" at 100 yards all day long. It will never wear a scope again. I have fallen in love with it's iron sights, and almost nothing is better than shooting from a standing/unsupported position and hitting what you aim at.
I won't get rid of either of them.
