If they were mine they'd never ever see a jacketed or plated bullet . All listed will shoot very well with lead . The 45 might take some work as it's not uncommon for them to have oversize cylinder throats . The 44 specials will show very good accuracy with lead & less than 1000fps . The 38/44 mine is quite accurate with the Keith designed 358429 or wadcutters . I've shot the Keith loads with 2400 in it for years . but now days use 4227 with the same bullet . Older barrel steel was not as hard as current production barrels . Use of jacketed bullets will accelerate wear & added powder needed will also contribute to wear . Older guns were made for cast bullets at sedate velocities .
