I've used both Oregon Trail and Missouri Bullets for paper punching loads. I've had success with both, but use mostly MB now because of the cost savings. The 38 Special bullets can actually be pushed pretty hard (for 38's), assuming they fit your gun well enough. Don't get too much leading, just some minimal stuff, but that's because they aren't quite a perfect fit for my gun.
I haven't tired their 357 mag bullets yet. Though I have tried their 500 S&W Crushers along with the 45-70 Buffalo bullets, which both have the BHN rating of 18. The 500 S&W bullets work pretty damn well. I've pushed them up to around 1400 FPS without leading, but they fit my gun pretty perfectly. The 45-70 Buffalo bullets are about .001 undersized for my gun, and when I start to push them up to 1600 FPS they start to lead a little. Nothing terrible, but still there.
I don't know if I'd hunt with them though.
