I've always used Redding 357 Maxi dies for all my 357 Mag & Maxi loads (I shortened the maxi seating die so that it would work with magnum cases).
The Redding sizing die is on the tight side, squeezing the case down to 0.3725" or so. That's great for the neck, because it grips the bullet tightly. But for the rest of the case it's way overkill, working the brass more than necessary.
One solution is to partial size cases. But when I've tried, cartridges were occasionally difficult to chamber.
So ..... I made a homemade sizing die that still sizes the neck to 0.3725", but the lower half of the case is only sized to 0.378".
Does it shoot any better? No. But it seems like the cases don't have to be trimmed as frequently as they used to.
Of course the homemade die is not carbide, so cases have to be lubed, but that's no big deal. I use hand lotion as a lubricant -- just squirt a dab on the reloading bench, dip my finger in it, and rub my finger on the case neck as I pick up each case. The hand lotion dries quickly so it doesn't need to be cleaned off the case, and if you get it on your hands, well it just makes your hands feel better.
