John as of recent (after the scopes were added barrels were re-regulated) every barrel when cold shoots exactly at the point of aim, while shooting one after another there is some direction difference between barrels - the slower/heavier the load more spread there is - with 154gr at 3120 fps it is none while with 293gr at 2280 fps the left barrel shoots app 15cm to the left at 100m. At close range out to 50 m doesn't mean much.
