Depending upon what you are doing, I have gone to 20:1 bullets for a lot of my shooting and I like Desperado and Matt's for that but they aren't cheap. I have had a lot of success with Rim Rock. For harder bullets, they are great and I've loaded a lot of their 200gr. .45's and 158gr. .38's.
In general, I have had the same success with bullets from Summers Enterprises, LLC and the price was tough to beat. Rim Rock has their line of wadcutters in virtually every caliber and those are great as are their line of Keith SWC's and others. For the .38 and .45 bullets the OP is asking about I would look at Summers.
