This is great data and shows that others are actually doing what I have been doing since I was child and proves/validates what you are doing now. I was doing the 375 to 9.3 about twenty years ago, very successfully I might add.
I started down this swaging road, as I said as a child, swaging .358 rifle bullets and putting them in a .357 revolver and a 9mm pistol, graduating to all manor of cal conversions. I will say this, generally speaking, one can swage down, at least, one caliber. I have done Gobs and Gobs of .451/230gr ball bullets to .429, putting them in my 44 mag with NO ill effects. Now some cal step downs, in some bullet designs are going to split the jacket and may not perform terminally as advertised, but I say it again, generally speaking it's of no consequence, in my experience, of course one must exercise caution and wisdom..
