Thread: 1 shot groups (cold bore challenge)

My mate since passed away, would shoot two rounds into the bank before he went hunting. He knew his rifle would group well after those two fowlers, my old 303 would start to wonder after a few shots so I would only shoot one shot at a target to zero it in. I’m lucky with the rifle I have now very lucky in that its first shot is on the money.
I’m very interested to test the multiple position one shot group as I’ve always wondered if a change alters my zero. I’ve never missed a dear but have not always hit them were I thought I aimed.
