Well, it was pouring like heck here today and boredom has set in. I remember a post on one of the forums about the accuracy of the graduation marks on BH209 tube - how accurate they might be if used for measuring. So just for drill I decided that what the heck let's find out!
I always load with a volume measure and over time I think I have become very consistent at using the measure... I also decided besides testing BH which I use sparingly I would also test T7-2f for volume.
Here are a few pictures that show the process I was using:
And this is the table that was created.... Hope the table makes some sense...
Not sure if this shows anything of much interest but it did keep me busy for awhile...
