Well my new set will be here Monday Everything ready to load. Redding dies for the .38 S&W are over $200.00 probably a special order. On a Whim, I just got out the ammo I have and took measurements.
Winchester Western: Mine are a bit longer but except for case mouth bullet diameter (mine are a tad bigger) all other measurements match. No roll crimp here ??

Remingtons new 'WHEEL GUN' offerings are pretty much off a bit, all the way around.

When the new dies arrive, I will endeavor to match the WESTERN offering (WHITE BOX? date) in every way I can. If able to do so I am hoping the end result will fit every gun, and be right on target. We shall see. This box of ammo came with one of the 1920 gun, along with a 'Hunter' holster-- two rounds missing from the box-- I have not fired any of them.
