when it comes down to the question of ,will i be hunting with a clean gun or a dirty gun ,i would have to say it will be a clean gun.so the shot from a dead cold clean barrel is the shot that I'm concerned about. i will be doing some experimenting to find how well the gun shoots with a clean barrel which means cleaning between each shot. the first shot is the one that mater's.
in my last session of shooting using Remington's 209ml primer i never swabbed the barrel once and shot it 15 times.
encore 209 50
T7 powder
