My 32-35 M16 Maynard has a crescent butt plate. A guy at Old Colony, (CRS), has/had a Maynard flat butt plate that was a direct replacement for the crescent. I was able to switch back and forth, easily, but was never able to talk him out of the plate. It worked fine for prone at 600 yards, the crescent plate was amazingly painful.
If I were shooting the Maynard any more, I would take off the crescent butt plate and somehow make, with tape and clay and ?? a rubber = RTV silicon butt plate that fit the gun. Probably with no screws needed. This is pretty easy to do. Switching back and forth would be easy.

Or, as U've done with the Gemmer/Hawkens, made a lacwe on leather butt pad. While looking old on the outside, if you contour some closed cell foam or similar inside, it will do wonders.  Ya gots to be able to enjoy you rifle.

I just switched one of my CPA's to a Cresent plate.  We have a monthly club match offhand at 200 yards on gongs that's "No Schuetzens no Breech Seating"  It was first set up as a BPCS rifle, shotgun butt. Fine for the 3 prone legs but offhand  on Chickens muzzle heavy and the plate wanted to walk around my shoulder.  Later converted it to a Schuetzen, Stevens 52 stock a very good offhand stock style. It's 38/55 and shot it black powder breech seated with good results.   

I have another CPA Schuetzen set up so wanted this one to fit the club rule and be a good offhand rifle.  Was apprehensive but have to say it's been a real good set up. I shoot about the same scores with it fixed ammo thumb and forefinger on the action and forestock as it did when Stevens 52 stocked using the palm rest.

On pulse, best trick is lots of sweatshirts if match rules allow.  Silhouette extra sweatshirts are not allowed and you get used to the pulse. It's distracting more than a real handicap.

Have the same problem. Is even worse when shooting from the bench or strapped into the AR in the sitting-rapid position. I've found that the Limbsavr recoil pad works well and does as advertised. I use the model that goes over the shoulder rather than on mounted on the stock.
