I recently received a Savage 300 win mag and had a leupold scope put on. I took it out to sight it in. First two shots from 200 yards touched about 4 inches high. I lowered the sight and next shot was at 4 o'clock, an inch or two out. Fourth shot was 9 o'clock, two inches out. Then, it looked like a shotgun had hit the target because it was all over the place. Thinking it may be operator error, I changed the target and had somebody else shoot. First shot, dead center. The next three shots, all over the place. I checked all of the bolts on the scope and they were all tight. Each shot was within a minute or two of the next, except when we changed shooters. There was probably 10 minutes when we changed shooters. I have talked to two different people and they said when sighting this gun in, shoot one shot every 5 minutes because the barrel gets too hot. Anyone else hear this or have this problem? It is a sythetic stock and isn't a floating barrel, whcih probably helps to retain the heat.
