WARNING: The information described on this page is for amusement only! Actually doing any of the following is dangerous to life and limb. The data on this page has NOT been tested in an instrumented test barrel and thus I have no real idea how much pressure the loads are producing. These loads could damage or destroy your firearm and possible even damage or kill yourself.
