First make sure your barrel is completely free of any oils before shooting. 90% Rubbing Alcohol works ok for this. Then pop a primer or 2.
Load and Shoot.
1 patch flipped once with 50/50 cheap Windex and rubbing alcohol mix (lightly damp) between shots. Follow up with a dry patch flipped once. Pop a primer if you got it too wet and it got in the breach plug.
Fire and repeat.
BTW a bullet not seated on the powder is no longer a bullet, its a barrel obstruction.
