Since there has been some discussion on the forum about this I though I would post some pictures from yesterday afternoon sighting in two Horizon built 300 Win mag's.
First picture showing speeds... One shot was clean/cold barrel.... I assume Derrick cleaned it.
Now the 3 shots with data.
Took off the chronograph and fired one more to see where it would impact.
Not much change.
Then I switched to a different 300 WM and fired 3 shots with and two without and you can see results. I was aiming at the hole punched in the target.... I missed....5 times
