I've fired Atlanta Arms 148gr. coated wadcutter. I don't like it very much. It is accurate and performs well, but it is a filthy round! The last time I used it, it left the chambers of my 686 coated with a thick black residue that I found next to impossible to scrub out. It took a couple of hours of brushing with a bronze brush wrapped with bronze wool to finally get rid of the buildup.
