Hello,
Quick question for you gun experts. I was sighting in my 12 gauge using the LeadSled, after getting it perfect at 75 yards I brought it up to 30 yards and shot freehand. I hit about 6" low and 6" left. So I took another shot, and put it next to my first show...low and left. Frustrated, I put it back on the LeadSled and shot dead center. Now really frustrated, I shot again freehand and put a slug low and left. Using my last shell, I shell, I shot freehand again and put it in the same group.

Does this sound right? I understand I could have flinched...but I find it hard to believe I flinched 4 times the exact same becaue I had a nice group...it was just low and left of the target. So my question is, can the gun shoot differently from the leadsled to freehand. I didn't think so, but I'm an avid bowhunter and don't mess with guns much other than for deer and turkey hunting. Incase it matters, here is my setup....

Remmington 870
Hornady sabbot slugs
3-9 Leupold VII scope.

Thanks in advance
