1861 Springfield, Whitacre Barrel

The Equipment: 1861 Springfield Manufactured in 1862, Barrel By Whitacre's Machine Shop, Winchester, Va. David Whitacre is not only a machinist, he is an artisan. He provided a 40 1/2" barrel with 1:72 twist and progressive depth rifling. The rear sight is a perfect copy of the original, the front sight is dovetailed and quite tall.
I am no marksman, My eyes aren't as good as when I first had them lasered. It is hard to see where the top of the black front sight is. It needs a bright spot at the top. I knew that it would likely shoot low with that tall sight. I picked my POA at the top of a rectangle 4x4 1/2" rotated 45° and got lucky a couple of times. I think I probably have the windage set pretty close but will need to work with a benchrest and be able to locate the top of the sight to adjust the elevation.
The Load was 60gr 2f Schuetzen Black Powder and 512gr home cast Minié ball lubed with beeswax and lamb tallow. I try to remember to tip the musket to the nipple side when loading. That doesn't always happen and the result may have been a hangfire on the first round. The passage had been cleaned with a pipe cleaner before loading. The 7th round was difficult to ram but for some reason, the 8th wasn't so bad.
I was wrong about round #4, it hit about 4" low and on center.
