I have one of those in .243 win. with a burris 2-7x scope. It will smack the 4" steel gong(200yds.) 1 shot right after the other using store bought federal 100gr loads. Its only sighted in a couple inches high at 100yds. 44mag aint gonna compare to that trajectory(or any revolver for that matter). Those barrels were made all the way up to 300 win mag. Can you say wrist rifle. If you still have that after the tax money is divied I may take it off your hands.
