Loose neck tension

I just started handloading for 30-06 and have a set of Lee dies, FL and Neck. Both of these dies over size the neck enough that Nosler BT's cannot pass a push test no matter how the dies are adjusted. I noticed the bullets seated very easily.

My question is, will a medium crimp with the Lee Crimp die make the 30 rounds I loaded safe to shoot in a bolt action?

I'm building ladder loads and can load them singly into the action to prevent set back. I could pull them but the BT gets damaged when I do so I don't want to pull them.

I've been loading since the late 90's and have never had this problem with Lee dies in other calibers. I know the sizing spindle can be resized .001 or so but I can't do this myself. What a hassle.

Questions . . .

Will the dies provide proper neck tension on bullets other than the Nosler BTs?

Do the BTs perhaps measure slightly undersize compared to other bullets?

They measure .307 with my calipers. I seated a Hornady Interlock and it was the same.

I'm trying to work up a sub MOA 100 yard group with a mild load and have a feeling I should just pull these and send the spindles off to Lee to remove .001

I use Lee Dies for my 30 06 rounds for my M1 Garand and have not had any problems.
Perhaps a using a Lee Roll Crimp after seating your bullets will solve your problem or you can try sanding the die's expander with some fine emery paper. It won't take much sanding on the expander to increase the neck tension on you bullets. The expander may have a build up of carbon on it.

I've always used a tapered crimp on my rifle cartridges, a roll crimp on my pistol cartridges. Not sure if I follow you though.

You should not rely on the crimp, the neck tension shuld be tight enough to hold the bullet.
Contact Lee, they should be willing to correct the dies. Why I usually buy RCBS. I have a Lee Carbide .45 die that doesn't size the case down enough to hold the bullet. Lee should take care of you on warranty. Note RCBS and the other guys even give you lock rings.
