I have a Savage 11 LRH .300 wsm that I have now only taken to the range twice. I have around 100 rounds through it total. It's got Leupold rings and a 5x20 Nikon Monarch on top...... Took it to the range today. Had several different types of ammo. It started out grouping GREAT; around. 75 MOA @100. At 200 it also grouped great. About 20 - 30 rounds in the groups really started opening up. Around 2-3 inches @ 100 yards. Checked the mounts and rings and they were fine. My questions are: If the barrel was too heated up would it cause this? Would the torque of the front action screw cause it? I had it torqued at 40 inch pounds...... I'm pretty darn frustrated as hunting season is approaching and I'm running out of time to get this straightened out..... Any thoughts or comments would be greatly appreciated!
