Jam into rifling.

[Quigley]

Some of the vld style bullets will actually shoot better jammed into the lands. Usually it is only .002-.003”. Jamming the bullet .020-.025” into the lands would just make it extremely difficult to close the bolt. I’ve only ever had one rifle that shot well with the bullet .002” into the lands. I’ve had several more that liked “kissing” the lands, but most like “just off” the lands. For a hunting rifle with standard bullets there is no need to jam the bullets.

I was reading up on my bullet selection, nosler rdfs. Alot of guys are saying they shoot them with .020 jam. I was thinking what in the world is the difference between .010 jam and .020 jam. Seems like jammed in the rifling is jammed into the rifling. These would strictly be target loads not for hunting purposes.
