And while grouping is good, they have been 2" lower than point of aim consistently. So I am trying a heavier bullet.

You really don't have much to worry about regarding pressure, heat treated chambers or not. There is a lot of steel around those .32-20 chambers. The problem is more in cracking the barrel in the forcing cone area (if your barrel has one). You can load to a MV of 1000-1100 ft/sec without concern, but it is best to keep it below around 900. A chronograph helps greatly in load development.
