When I,m sighting in I wipe the barrel after every shot. And I don't like pelets I like the powder. The reason for this is that every gun is different in what it likes for a load and the difference in accuracy in just 5-10 grans can be a bunch. One of my guns may use 85 another will use 110. And if I try to use 100 its no good. So you see what I mean. I try to keep my shots within 100 yards and 80 grains of powder has worked just fine for me.Also when you get your gun real close not only clean it between each shot but let it cool all the way down. You will see a real difference in a shot from a hot barrel and a cold one and when you are deer hunting you are shooting a cold barrel.I hope this was some help Good Luck Mike
