I was putting the finishing touches on sighting in my Henry Big Boy Steel in 357 mag today. Things went well at 25 and 50 yards with decent if not great groups.
When I moved to 100 yards, everything went south on me.
I was holding well and seemed to be getting off the trigger well but the group just wasn't holding at all. The target was a sight in with the squares on it in the quadrants. they were already on the target board so I used them since no one else was using the range.
It looked like the rifle was shooting 6 inch groups or larger and I was seriously disappointed.
I went down to the berm to collect my target and come to find out, the squares on the target were miniature. I am not certain how small they were but I put one of my targets that had one inch squares up next to it and there was a lot of difference.
Turns out my groups were in the three inch range. That made me feel a lot better about things.
