Thread: HELP! Can I resize loaded ammo?

Well it's got me buggered, definitely not a projectile seating issue, I have now run some of the loaded rounds through a small base sizer without the decapping stem and the bolt still won't go into battery, I have used vivid to try and see where they are tight with no obvious results, factory hornady ammo fits fine. I have measured case length and outside neck size.... They should bloody fit!
I've put them all at the back of the cupboard out of sight!
Cheers everybody for suggestions.
