Took my new 44 mag to the shooting range today to sight in the scope. Took 2 shots, adjusted scope and repeated. The first 5 pairs of shots grouped well relative to each other. However, from that point on, the shots tended to scatter. Maybe the barrel got too hot?
Also, this was shooting the gun right out of the box (no cleaning). Didn't know that cleaning was recommended before shooting. I'll clean the bore before I go back to the range.
