Thanks for thoughts, I had one Rounded on a 3 inch Packer many years ago, no ERH on gun (never a problem with that on this sort of a specialty rig kept in front of heavy velcro vest, while fishing in bear country).
Anyway, this Rounded Butt worked out Extremely well for my hand but it does have an extra short bbl. Noticed for me, with heavy recoil (which dont do alot of now), gun slipped just perfect (or right amount) in my hand. Course different loads & powders can change recoil too.
Was just curious if any experience with longer bbls, any length yet under 5 inch may be best? But curious about 6inch & 7.5 bbls too? Yet light to moderate recoil too.... existing grips work very well most times am thinking, on m83.
