Just a quick update on this project.

I managed to get out to the range last week. I had a day wide open before loading up the truck for the 750 mile trip to Minnesota to see our new Great Grandson.

I tested the Hawk .304 180 bullet. I started with center of mass point of aim. The front bead covered the center bull. I got a group of 5-1/2 inches. I could not discern if the front sight bead was larger or smaller than the bull in my sight picture so I switched over 6 o'clock hold.

I fired 5 shots for a second group. The first three shoots were spread horizontally about 3 inches. Shots 4 and five just flew away and this total group size was also 5-1/2 inches. The barrel got unbearably hot-hot enough to cause me to swear when my little finger touched it. .

Air temperature was over 90 degrees. I was using IMR 4064 which is temperature sensitive.

I decided to discontinue testing until the weather cools down,

I had no issues with pressure.

As you can see above my photo links are dead. My photo hosting site was destroyed in the cloud fire in France last spring.
