You are doing realize that any time you alter the temperature in the bullet by that Intense of the mount the Bodily dimension of the bullet truly imr enduron powders modifications. It’s No surprise the velocities had been unique In the event the diameter from the bullet is .003″ unique at Those people two temperatures.

That’s an awesome query, Kasper! During the barrel exam I done recently, I measured chamber temperatures in excess of a twenty spherical fast-fireplace string (all fired in 1 moment) and a fifty round slow-fire string (fired over twenty minutes). The temperatures I recorded weren’t as superior as you may think they'd are already. Even about the immediate-fireplace check, the best chamber temperature I found was 149° F.
