Juan Tedman, the 356 is reloaded using 358Win dies. It is essentially a rimmed 358Win but with slightly less velocity. Certainly more then a 35Rem so that's not bad territory to be in. It never caught on for whatever reason (there are many, IMO). I feel you'll get a flatter trajectory with similar weight bullets then what the 375 will do. Both are better then the paper ballistics.
