No one knows which is widest because not everyone measured them. They just reported which ammo brands they had problems with. This is the list of ammo that people reported having problems with:
Blazer Brass .38 Special 125 gr. FMJ
Magtech .38 Special and 357
Armscor .38 Special 158 gr.
WInchester USA white box .38 Special
Hornady Critical Duty 357 (3/6/18)
Blazer Brass .357 (3/20/18) Woody Hayes in comments
Tula (3/20/18) Woody Hayes
GECO 357mag (6/14/18) giantpune
Vollmantel FMJ .38 special (10/24/18) Linda Goodman
That doesn't mean that everyone who tries this ammo will have problems or even that the people who reported problems would necessarily have problems with a different box of the same ammo. Even in the same box, rim diameters will vary a bit. Rim diameters are specified to have a dimension and a tolerance. The max diameter is 0.440 inches. Most people reported having problems with rims that were larger than 0.436 inches. A 6-shot will not have problems with a full load where all the rims are at max diameter. I doubt that any of the 7-shot GP100s would do the same, but the chances of that ever happening is close to zero.
I highly doubt Ruger will give you any trouble if you ask them to replace a 7-shot with a 6-shot.
