I pass a couple of clean patches through, then fire a cap or two to clean out any cleaning/oil residue. After that I pour about 10-15 gr of powder down the barrel and keep the barrel pointed straight up. Then fire a cap pointing at the sky (no sablot or bullet, just the small load of powder).

Then I swab with a patch and load for the hunt. I have yet to have a gun that will shoot the same fouled or clean (own five) so I just do what the gun tells me she likes
