Semisane,
Do you have any issues with your first shot out ofa clean barrel not shooting as straight as say your 4th or 5th shot?
Yep! In most cases the second shot is going to be two or three inches off the point of aim because Ihave mysight adjustedto the clean barrel shot. In a hunting situation I'm not really concerned about that. The big issue with this method is "does your first shot with a squeaky clean barrel go to the same spot consistently?". It takes a bit of doing to find out. You have to shoot a shot from a clean barrel, then totally clean the bore, oil it lightly, dry swab the oiled bore,load, and shoot it again - and do thisfor at least five times with the load you are testing. I've found at least one load in several of my guns where this method works. Hunting on a clean borewould not be the way to goif your gun is totally erratic with a clean bore.
