Tinker,
I would suggest a heel-base bullet for cartridge revolvers.
The heel end should be the dia. of the top of the lands. (this stabilizes the back end of the bullet)
The nose end should be the dia. of the grooves. (this imparts the full depth of the groove and rotation to the bullet)
Hollow base bullets work well in muzzle loading firearms. The hollow base bullet only has to expand once in these arms.
In a revolver not so well, because of the space between the cylinder face and the barrel breech, forcing cone and rifling all effect the skirt of the hollow base bullet.
Often time the soft lead skirt gets blown off or otherwise damaged at the interface between cylinder and barrel.
My best,
Blair
