To give you an ideal what I'm talking about.

Cut the '06 case to the length you want to make your round. Now measure the the thickness of the brass.

Get a piece of 45 brass and measure it. You'll find the 45 brass is much thinner then the '06 brass.

If you stick a 45 bullet in the case, it will bulge it.

What I did was to have a cutter (reamer) made a couple thousands smaller then the 45 bullet and reamed the '06 or 308 case (I used both) to the depth the bullet would go.

If interested, tomorrow I'll dig around the shop and post a picture and dementions of the reamer.
