RE: Nervous Newbie!
Having the bullet touch the powder is not a problem at all and is actually prefered as it keeps the powder "settled" and doesn't allow it to move around inside the case too mcuh. If there is too much air inside the case you could get varrying pressures, varrying velocities, etc... becasue of where the powder charge is in relation to the primer flame... IE shooting steeply up hill or down hill. There are many powders that when loaded the bullet will actually contact the powder enough to compress the powder charge. Of course, too much compression can be a bad thing as it can bulge cases and push bullets out of the cases over time.
