Single cavity wadcutter with a hollow-base. It was reasonably priced so I bought it. I had been using Hornady swaged .358 HBWC for years for target loads until Hornady stopped making them because of the Obama shortages. I bought a couple of different solid-base wadcutters and tried them. They were OK, but never quite matched the accuracy of the Hornady's.
When I found the 358395, I decided to try it even though I knew it would be a slow casting mould. It is. However, when I tried them with 2.8gr of Bullseye, they were even more accurate than the Hornady's. This is from a two different S&W K-38 Masterpieces. I have heard people say that the only time a hollow-base bullet improves accuracy is when the dimensions of the gun are wrong. The K-38's have accurate (matching) dimensions. Still, the 358395 is the most accurate bullet I have fired from them.
Best I can get from the 358395 is about 1-1/2 bullets a minute though. Its time well spent.
