It depends on what bullet you are using. With Berger's I try and get them as close as possible without touching. With my 243 it turned .75" groups into .33" but with a 7mm Remington Mag it did not seem to make a difference though. With Barnes I keep them off about .05" but to tell the truth I've never really experimented with different distances. I read .05" in a Barnes newsletter and the 243 shot .25" groups, so I figured I'd leave well enough alone. Keep in mind the closer you move the bullet to the lands the higher your pressure is going to be. If you are using a max load and want to move the bullet closer to the lands I would suggest reducing the powder charge and re-work up the load.
