I have been using the coated hard cast (18 Brinell) Ranger 158 gr RNFP to date. It seemed to make sense to use the harder bullet for the higher velocities. I find the groups start to open up quickly between 10 and 11 gr of Unique (I've since changed to Universal and the change happens between 11 and 12 gr or so in my rifle). I emailed MBC to see if I could get bullets sized to .359" and coated. They told me it was possible, but instead recommended I use the softer version of the bullet, Cowboy #15 with a hardness of 12 Brinell. The idea is that it would bump up easier and grab the rifling better and with the coating there should be no concern about leading. I'm still using up the first 500 but plan to try the Cowboy #15 when I reorder.
If I were going to use it for hunting, especially hogs or bear, I'd use a 200 gr JSP or the Hornady FTX bullet over LeveRevolution powder. I've loaded and shot some with the Speer JSP and they shoot well. Haven't tried the FTX for reloading but really like the Hornady factory ammo. Since the 158 gr pistol bullets are slightly smaller in diameter, they "might" suffer in the accuracy department, but I have no evidence to that effect. They also aren't necessarily built for full bore .35 Rem velocities. All this is part of the fun of rolling your own. Good luck.
