DECISION ON APPEAL
STATEMENT OF THE CASE
This is an appeal from the final rejection of claims 1-12. These are the only
claims in the application.
The claimed invention is directed to a breech plug for use with firearms such
as a muzzleloading rifle. Appellant’s breech plug has a generally cylindrical body
with a first end having a nipple to which a percursive cap is applied. The second
end of the breech plug has a stem of smaller diameter than the barrel. This forms a
cavity between the diameter of the stem and the barrel.
