OK... I had my HS Precision RDT on the bipod sitting on the table. I guess I wasn't paying close attention when I put it there and it was too close to the edge. As I stepped away it took a plunge off the table and onto my very hard terrazzo floor. It landed squarely on the scope and bounced around a little before settling. I was mortified! I picked it up and looked thru the scope and all seems well. I turned the turrets and they seem OK. It looks relatively un-scathed. I've seen "Nobody's" video about breaking in a rifle and that makes me feel a little better but terrazzo is damned hard stuff. What other things should I check before I see how far off zero it is?
