Hi Grandpamac, Thanks for that. What is vertical stringing? Not looking to shoot long range at this stage. Usually if the deer are a long way away, I walk closer. The shooting range close to me is 100m so would have to find a friendly farmer I guess to try it out at longer range.
Vertical stringing is where the group is much taller than it is wide, often but not always caused by variations in velocity. Horizontal stringing can be due to wind.
