Since I have no "big bore" snubbies (defined as bigger than .357") , I'll just share the snubbies I do have and carry. I used to have a variety of them to include Model 29 and 629 versions in 3", I never found them practical to carry. I use Remington 125 grain Golden Sabers in the L Comp, and carry it in a Sparks PMK. In the Model 27-2 I use American Eagle 158 grain JSP.
Model 27-2, 3.5", Spegel grips in Thad Rybka holster
Model 586+ L-Comp with Spegel grips. My favorite carry gun.
