I have used the Ranier 158 gr HP & FP coated bullets in 38/.357 with great results. Can't tell the difference in either as far as accuracy. Both shot very good in several different guns. I'm loading them light with 3 gr Bullseye. Was in Cabelas over the weekend and they had some of the Berrys HP in 158 with a pretty good price, so I picked up 500 to try. I don't think the HP affects the accuracy any over the FP but they do look cool. I have not tried to push them faster but I think they could easily be pushed to 1000 fps or higher with any leading problems.
