Forming 375 Win cases from 38-55 or 30-30 brass

Seems like this might be the best place to asks this question. I'm in need of Win 375 brass and its non existant. I can form 375 from 30-30 or 38-55 but have heard these cases will not stand the pressure of the 375. Can anyone enlighten me. I don't want to hurt my rifle or me....... thanks, roy

they are all based on the same case.
however the 375 is a higher pressured round.
you can use the other two cases in place of the 375 but you have to work within their limits.

I use .30-30s they come out a little short. So I just load two in a tubular Magazine, because the neck does not quite reach the crimp groove.
Yeah, I could seat the bullet deeper, but it shoots pretty good as is.
Don't have much need or use for the last 150 fps, so my loads are mild.

The difference was that the web of the .375 was thicker that that of the original 30/30 or 38/55.
