I did some dry firing recently with a custom built on a 700 action. I started out on a bi-pod with rear bag, the target was at 100 yds. I got cumpfy and squeezed it off while watching for shooter induced movement. Wow, there was 1/2 min of jump straight up. To make a long story short, this jump is caused by the movement of the firing pin. I checked another 700 and a 660, both of these exhibited the same problem. Generally the movement was fairly consistant, 1/2 min straight up; however in a string of ten cycles one or two would show 1/4 min. periodically there would be no movement at all or there might be a little lateral movement. I thought it was the bi-pod causing this so I switched to sandbags. This proved to be far more erratic and unpredictable. After playing with the bolt guns I switched to two AR style rifles with JP triggers. I was expecting them to exhibit more movement than the bolts guns. Much to my surprise thre was no detectable movement from these rifles when dry firing from bags or a bi-pod. I said all that to ask this. How much does this movement affect accuracy? Personally I think the movement has occurred prior to the bullet exiting the barrel. Your thoughts on this matter would be appreciated.
