RE: swabing between shots?
I simulate hunting conditions only after I am positive that I have the best possible accuracy out of the projectile that is possible. For this reason I swab between each shot, to make the next shot as consistent as the one before it. Once the load is worked up, then the practice can begin.
When I want to simulate hunting conditions, or now that winter is moving in and it gets harder to move the bench equipment around the range, I go back to the shooting sticks. With the shooting sticks, this is the way I hunt. I do 99% of my shooting while hunting off shooting sticks. It is at this point that I might shoot three even more shots without swabbing. Granted I do not expect the same accuracy as when I am pounding them off a bench rest, but it does give me a good indication of what I will see in the woods.
