I thought about trying some 38 TJ and 38 Comp brass from Starline they say the feed smoother with rims turned down (comp & TJ brass) I have not had any problems feeding due to rim hang ups.
hopefully this Sunday out at the club I will get a chance to fire mine with some new loads for it. I still have not laid my hands one any Lil' gun powder, but have of little bit I got from some friends so I could give it a try.
