yeah i had the nut flush with the end of the threads but I assume maybe it was off a little and mushroomed a little. I tried to file it a little but i guess i just have to keep working at it. I dont have a die that big either so i guess thats out. Yeah if they are mashed it is so slight that i cant really tell but enough to make it very hard to put the nut on. I'll keep at it. thanks
