Does anyone have the dimensions, either the mag tech or the solid
turn down ones. I have a friend with a lathe that I might be able to
turn my own(personal use)

Same on the outside as a paper or plastic one. ;)

What about the inside diameter?

One gauge larger, 11 gauge for 12, brass shells use one gauge larger than paper/plastic.

'em brass ones are bigger on the insides.  Also, brass has a different rebound than plastic or paper.  So, yer goin' to have to experiment with yer loads to get the best patterns.  With Holy Black, yer pressures should be ok, but ya will want to shoot some patterns to get a reading on how they spread.

A word of warning for using brass shotgun hulls.  If you use the traditional wad column of powder, nitro card, cushion wad, shot and over shot card you may find it difficult to develop any sort of a pattern from modern shotguns. The modern guns have a long forcing cone that does not go well with the above column. They are cut to be used with plastic wads. I was shooting 20 ga and a Remington Spartan and could not get a good enough pattern using the traditional wad column to take down a KD. To make it work I had to go to a plastic wadcup and finally a plastic wad over the nitro wad. Completely defeated the purpose of what I was trying to do.
Now I shoot a 12 in a Spartan and grit my teeth and use a plastic wad out of plastic hulls.

Victor,
Magtech brass hulls are drawn therebye having the grain structure that allows the brass to expand to seal the chamber.
If you take the advise given already,with machine turned hulls two things can,and probably will happen. (1) you will end up with split hulls and (2) gas will escape between the hull and chamber wall eventually pitting the breech face or worse.
The correct way to turn brass hulls is first make a plaster of paris cast of your chamber pushing it out before it goes off to much.
measure it and make your hulls as neat a fit as you can,even marking the head for the barrel it fits.
The inside should be as near to your bore size as you can get.

Victor and anyone else that may be interested,
One other small piont about Magtech brass hulls.
This type of thin walled hull used to be called Brass perfect. They were designed for chamberless guns. They can be used in guns with chambers but the disruption caused by the forcing cone (squashsing 10ga down to 12ga ) causes very eratic ballistics.
