I have experience in decapping live primers also, but I'd suggest an ENTIRELY different route for you to skin this cat.
.45 Auto is a (relatively) low pressure round. It doesn't run the ragged edge of sanity. I think in your position, it's a better idea to use the brass as it sits right now and make some starting or mid-range loads with them.
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.
