[QUOTE="TheDerkster, post: 1196250, member: 92447"] The 7mm SS Mag is a cartridge based off the 7mm SAUM. Its been improved with a sharper shoulder that is pushed back so that you can run long bullets in a full length mag. My 195 EOL just barely fits with the 7mm SS, so i doubt it would for sure in a 7mm SAUM. The case is trimmed to 1.95." The process is simple really. Get a 7mm SAUM FL sizing die, shorten it about .16-.17 inches so you have some room to play with. Set the die so that the brass is just barely short enough to allow the bolt to close. You want just a little bit of crush, but not so much you cant close the bolt. Trim the necks as well to about .0135 or so thick. If you use an outside neck turner, youll need to run them back through a sizer to get the necks to the right dimensions. I think the inside/outside turners you probably wouldn't have too. Youll have a pretty good sized donut youll need to get rid off that was formed when you push the shoulders back since the brass flows from the shoulder into the neck. Load up with about 8-9 grains of Titewad (Charge varies with powder), put a piece of tissue or toilet paper ontop of the powder, and then top with 2 minute cream of wheat. To seal up the neck, fill it with wax or more tissue/toilet paper. I used a candle warmer and poured wax it the necks. Worked good and smelled great! Trim to 1.95." Then your done. The only real extra step over normal brass prep for new stock is loading the powder with COW and wax to start fire forming. I neck trim, chamfer flash hole, length trim, and full length size anyways. You end up with the way they should have designed the 7mm SAUM in the first place. Im tickled with it. You can get Norma brass from midway for about a $1.52 a piece. Rich has it in stock as well. His brass looks much better than mine. I didn't have a very good trim on my necks for some reason. He also has the dies and everything in stock. He sells the Whidden dies which are super dies, and even if you have problems, they are extremely willing and happy to fix anything that might be wrong. Rich also has the reamer and go gauge as well by the way. [/QUOTE]
