I see vertical from inconsistent loading of the rest than anything else. It seems to be especially prevalent with injection molded stocks that will flex to much at the wrist. Second aspect is to check the float on your barrel by putting a small ball of clay between the stock and the barrel. The clay compresses down on the shot and will quickly tell you if there is enough clearance for your stock. I shoot from the ground with a bipod and rear sandbag for both competition, load testing and most of my shots on the field.


Hunt hard, kill clean, waste nothing and offer no apologies.
