Give us a LOT more information. Tell us the gun (we are guessing it's a 1911!) and tell us the bullet, the powder, the charge weight, the equipment you are using, etc etc. We'll see what we can trouble shoot.
You almost cannot include too much information.
Attention Brass rats and other reloaders: I really need .327 Federal Magnum brass, no lot size too small. Tell me what caliber you need and I'll see what I have to swap. PM me and we'll discuss.
