.44-77 and paper patch?

[Kurt]

Jim before you clamp that block of iron in your lathe and chips start flying you might want to rethink your base length length at .1350" a little.
You have it at .1350" and you say that you only seat that bullet .100" in the case. Using your .007" thick paper your not only adding to the dimensions of the base shank but also 7K to the base and also to the front of the taper. That has a lot of frontal you have to push into the .0438" bore. My rifle does not have .050" free bore.
