I have to disagree. Ideally you want a bullet that will push through the cylinder with minimal pressure, thus a bullet that is same as or VERY slightly under the size of the cylinder throats. You also want the throats nearly the same as bore diameter. If throats are tighter than bore diameter and bullet is larger than the throats, a lead bullet will swage down to throat size and be undersized for the bore. Accuracy suffers and leading usually occurs. Not as big of an issue with jacketed as they will “spring back” after being forced through the tight throats.
I am offering a possibility for the “hard to eject empties”. If the cylinder throats are too tight, pressures rise. In magnum loads the pressures may be high enough to cause sticky extraction. The fix, if this is the case, is to have the cylinder throats opened up to proper diameter. This is easily done.
Another possibility is dirty or rough chambers, another fairly easy fix.
Worse case possibility is oversized chambers allowing brass to expand too much, making them hard to eject. Doubt this is it, but only fix is new cylinder.
Since you had no problem with 44 Special I’m guessing it’s a pressure issue. All just guessing though without seeing the gun or the fired brass.
You can contact Fermin Garza and he can thoroughly check the cylinder for you.

Good luck with a great looking revolver.
