Never had mine work with them seated in the lands like the VLD's seem to like. Of all the calibers and sizes of Amax that I've used (about 8) they all have worked the best starting from at least 0.01" or more.
Keep in mind that the closer you seat the bullet to the lands the higher the pressure gets typically. Obviously you want to be careful and work the load up. Tight fitting chambers usually benefit land touching bullets while my factory sloppy ass chamber works well in conjuction with mag length rounds.
