Bob,
Mild Trapdoor Springfield loads like factory Remington or Winchester 405 gr. will not be abusive in either gun. Factory Remington runs 1110 fps from my 12" barrel Hunter Contender barrel. Load a 400 Speer to 1350 or more fps, and it's a bear.The same heavier load in my 6 1/2" gun is unmanageable.
As to whether a Contender is better or worse than an Encore for felt recoil, I'd say that generally the extra weight of an Encore helps greatly to moderate the felt recoil. However, if your fingers are short, it may be necessary for you to reposition your hand in such a way on the Encore ( to reach the trigger), that recoil is driven more into the first joint of your thumb, thereby increasing the pain on heavier loads.
I agree that a T'SOB and a Leupold are the way to go.
