I figured it had to be one of the three, but didn't know if factory uses a specific brand. I guess I'll get all three and try each one to start. The guy at the range said it might be my scope. It's a Cabela's Alaskan Guide 3x12 w/30mm tube. I'm not sure who makes it, but the clarity is good at low light and I gathered from the ad that it could take the abuse of magnum rounds. Hopefully, changing the round will clear my patterns up.
