Have one for a while now, at first had problems feeding HP but I just kept working the action with some authority and at times will give it a fast double action throw to get it to feed. Now I have no problems feeding and ejecting the .357 HP. On the other hand regarding shooting the .38 specials...no problem feeding the HP...but ejecting them most of the time I have issues with ejection. Not really sure what causes this, I think it has to do with the .38 rimless case groove not deep enough for the extractor to get a hold off as compared to the .357.
Another known problem I Beleive only with the early productions are the factory sights, they maxed out on adjustment and could not even get on target at 25y, approximately 6" off the target. Some research pointed out Steve gunz has these correct sights specifically for the rossi ranch hand, and works great now. If your willing to spend a little more I would check out Chiapas version seems to be of better quality.
But once you get them to work, their a blast to shoot
