I was at the range today with my new to me Remington sps tactical rifle in .308. It has been a warm and sunny day and I was shooting at a fairly quick pace. After 15 shots I gave up for the day because my groups were getting progressively worse. I told my story to an old guy at the range with more experience than I have and he told me my gun was way too hot. He said to keep the rifle in the shade and pause for several minutes between shots. I don't know if this makes sense or weather to blame my wet noodle black plastic stock that rests on the barrel under my bipod. Not too impressed with my purchase so far.
