This will be exclusively for moderately hot magnum loads in both the rifle and the SA revolver. I'm using most hard-cast 125 and 158gr, but also looking at moving up to a 180gr GC for possible short-range deer (with a strong possibility of mt. lion). Unfortunately, my long-time favorite powder hasn't been on the shelves around here in over two years.
By the way, .38/.357 are identical in every dimension but case length (the magnum case is 0.1" longer, to prevent accidental loading in something chambered in .38spl - there is a collossal difference in chamber pressure). But you can use the same dies - I do! Just have to turn 'em down a bit more for .38
In shorter barrels, or in tube magazines, crimp is important. I've done quite a lot of both, this is just my first time loading .357 for a rifle. And I'm out of my preferred magnum powder. (2400 worked REALLY well in cast bullet/gc loads in the .30-30. But now, I need to find a substitute.
