32 guage works great. First you need dies. These can be had from CH 4D. You should also get the form and trim die. you should be able to get the 4 dies for under 200.00. This may seem like a lot compared to Lee, but it is really not bad when compared to RCBS. Also the folks at CH are really great to deal with. The other thing you need is a piece of 7/16 stock, driil rod is ok. This will be used for a mandril when you form the brass. What you do is you trim the brass to about 2 inches and make sure to clean up the rough edges. Then you set up the full length sizing die in your press.[a good press such as the classic cast is a good idea allthough the first ones I formed on a Lee turret press] when the die is set up and adjusted remove the decaping rod. Now lube the outside of the brass,I like imperial size wax the best. Now place the brass in the shell holder. What you need to do now is put your piece of 7/16 stock through the top of the die and let it rest in the bottom of the brass . Now in one motion, run the brass up into the die. The neck will form niceley on the 7/16 stock. after this move the formed case to the file and trim die. File to length in the form and trim die, and if you do everything right, you will have nice 43 Egyptian brass. The thing about 32 guage is that the brass you make will be closer to the right dimension then the bertram that is out there and will will cost a fraction of the money. Magtech 32 guage is around 20.00 for 25 and Bertram is around 60.00 for 20. you can also use 50-90 brass and follow the same procedure, but the case head dimension on the 50-90 is a little small. Use this info at your own risk.
