Thats probably the best suggstion that will work.Here is my works every time method. The way I make it is to click, "add to cart" at Cabelas for 17.50 a box or at Midway for 18.29 a box. Never lost a brass and the head stamps match what's on my barrel. I just prime them and seat a bullet. No other prep needed.
Where can you buy 300 Wby brass for $25.00/50???FWIW--back when you could get 7mm wby Rem brand brass I would make my 270 wby brass out of it--it came out excellent and didn't need fireforming or anything--all shoulder dimensions perfect----THEN I tried going one more step taking down the new 270wby to 257 and couldn't do it....at least with my dies. I just wound up with crushed shoulders. I see some outlets are carrying hornady match quality brass. I've been buying the 300 wby brass at about $25/50 and it is wonderful stuff. And I see listed by the same people "hornady belted magnum brass". I wonder if this is something that could go through a die and become almost any belted caliber without alot of screwing around. It will be interesting to see the rest of the responses to your question as I know people have worked with 7mm mag brass. One last hint. I've notice that when reworking brass it's always easier to rework brand new never been fired brass over even once fired brass as the neck area definately takes on a "hardening" even with one firing.
