What, you said you were lubeing the inside of the case???? Unless it`s something like mica or graphit you could be screwing up. You wnat to be carefull not to get any lube in the case that could contaminate the powder.
Your next problem will be seating the primers. Mil brass has the primers crimped in and the crimp must be removed or you will find it imposible to seat new primers. This can be done with a hand reamer or on your press with a primer pocket swedge. If you don`t have a good heave press like the Rock Chucker you will find this hard to do also. That`s the main reson I quit buying mil brass.
