Yes it is do-able in a handi with an avg max pressure of 36000 but no handi barrel could be just re-chambered , you would have to have it re-bored and re-chambered both , the cost of this would run from $450 to $600 depending who does the work .
This would also be a way to avoid the over bore problems that the 44 mag has , yet still have one in a pistol round .
