When you scrounge, study, cut, and examine many different hulls over the years, you get a prety good idea what kind of hulls they are just by looking at them. Compare them to a "known" Cheddite hull and that tells you a lot. Sometimes you will get a loading booklet that tells you things that confirm your suspiscions too. The newer Hodgdon and IMR booklets provide some of that data if you look closely, but asking here is a good sourse too. Before taking what you read here as Gospel, it may behove you to do a bit of research for your self too. Actually compare the Kent hull to a known Cheddite and see if YOU think it is too! It's your head, eyes, fingers, and life you are dealing with here! :wink: In almost any situation I can think of right now, it really doesn't make any difference whether the hull is a Cheddite, Clever/Mirage, Fiocchi, or even a Federal paper base wad hull, they all load about the same. close enough that the difference is neglegable. Many times you will find data for all of those hulls listed together in one section or when comparing between sections, find the only difference is a couple tenths of a grain of the same powder and a couple hundred psi of difference in chamber pressure. How much difference do you think that makes? I probably have 50 or so different powder company loading booklets from many, many years past and present. There is a wealth of information in them if you research it a little.
