"I have since went out of town and bought another box of Shockwaves to use. What is the best way to site this gun in. Start back over at 25yds with the Shcokwaves and then move out? Thanks for the input".

Yes, start back at 25 with the Shockwaves. You'd be surprised at how much difference in point of impact can be attributed to seemingly small bullet weight changes in large-bore rifles. I learned this when working with the .45/70.....
