Effectively, Mike. It’s most likely not as big of the deal as you believe. Consider the velocity variations inside the chart I posted within the opinions. That male chopped a barrel down one inch at any given time, and recorded IMR 7977 muzzle velocities. Recognize that a 22″ barrel was just fourteen fps slower than a 27″ barrel.
Whenever we headed to the vary for any exam, we randomly selected imr enduron powders 20 rounds in Each individual caliber from your stock. We chronographed the velocities with a Caldwell Ballistic Top quality chronograph working with their Android telephone app.
