Well, I finally was able to get out and do some more shooting with the Knight Extreme. I had conducted an initial test of the Knight with a Lehigh Gen II plug installed in April and wanted to follow that up with a 'prove it' test. I have gone back to work so finding the time to get it done has been a problem, but the time presented itself today - so I headed to the farm this afternoon.
The April test really was ran to test the cleanliness of the new Lehigh Generation II plug. That issue is no longer and issue for myself so not going to speak to much about how clean the plug is, but it sure is nice.
The testing I was trying to conduct is how well the plug and vent liner work with BH. In my mind these two test confirm what i thought I already knew. The 'Vent Liner' is the key and the 'Plug' is clean in all of my Knights. For my tests to be complete I still need to shoot in some really cold weather and that will have to wait for awhile. Probably late December...
What I was trying to confirm is that different primers do not have all that much of an effect on velocities created or instant ignition. There certainly are dofferences ion velocities, but again I am not weighing charges - I am using a powder volumn measure and dropping that into the bore.
Here are the targets and the information... This is today's target
This is the target from April....
