I think when refering to the 357, marginal is a bad choice of words. Less than optimal is better. There is a difference. anyone who argues it is in-effective is stupid, it will kill deer. A bow kills deer, but I would not compare it to any gun in terms of ease of use an capability.
A 357 takes a higher degree of mastery to hunt with. hollow points penetrate less, so angles and range need to be really scrutinized. Hard cast leave pretty small wound channels.
A 44 is not that big of a deal to shoot. A 240gr bullet will take any deer or black bear at longer ranges and less than optimal angles. Step it up, 280gr hardcast, and you have serious capability (still relative to revolver terms). On a scoped revolver 100yds, quartering away is no prob. If recoil is too much, get a ported model.
I've shot with a 140lb woman who shoots and hunts with 454 un-ported without issue. Recoil is no excuse,.... pansies. lol.
